The effect of the substitution at sulfur on the stereochemical outcome of the coupling reaction, Category: catalysis-chemistry, the publication is Journal of Organic Chemistry (1993), 58(22), 6114-17, database is CAplus.

Pinacol cross-couplings of sulfur-substituted aldehydes with aliphatic aldehydes have been investigated. Addition of the sulfur aldehyde to a solution of [V₂Cl₃(THF)₆]₂(Zn₂Cl₆) and the aliphatic aldehyde provides unsym. 1,2-diols in good yield (55-97%). Stereoselectivity in these reactions is influenced by changing the substituent R³ in sulfonyl (R³SO₂)-substituted aldehydes.

Occhialini, Gino published the artcileCatalytic, contra-Thermodynamic Positional Alkene Isomerization, Product Details of C15H24S, the publication is Journal of the American Chemical Society (2022), 144(1), 145-152, database is CAplus and MEDLINE.

The discovery of a dual catalyst system that promotes contra-thermodn. positional alkene isomerization under photochem. irradiation, providing access to terminal alkene isomers, e.g., (2-methylallyl)benzene directly from conjugated, internal alkene, e.g., (2-methylpropenyl)benzene starting materials was reported. The utility of the method is demonstrated in the deconjugation of diverse electron-rich/electron-poor alkenes and through strategic application to natural product synthesis, e.g., (-)-nopinone. Mechanistic studies are consistent with a regiospecific bimol. homolytic substitution (S_H2′) mechanism proceeding through an allyl-cobaloxime intermediate.

We present a novel methodol. for the asym. synthesis of ¦Â-mercaptolactones via isomerization of ¦Ø-hydroxy-¦Á,¦Â-unsaturated thioesters by means of a bifunctional aminothiourea catalyst. The catalyst interacts with the substrate through the cooperative action of both a covalent bond at the amino group and noncovalent bonding at the thiourea group. The potential for an enantiodivergent synthesis could also be demonstrated by carrying out the reaction in a different solvent system.

Taniyama, Nobuhiro published the artcileSynthesis of V/Fe/S Clusters Using Vanadium(III) Thiolate Complexes Bearing a Phenoxide-Based Tridentate Ligand, Synthetic Route of 22693-41-0, the publication is Inorganic Chemistry (2014), 53(11), 5438-5446, database is CAplus and MEDLINE.

Vanadium(III) thiolate complexes carrying a phenoxide-based tridentate ligand were prepared from the reactions of V(NMe₂)₄ with the protonated forms of tridentate ligands (H₂(O,P,O) = bis(3,5-di-tert-butyl-2-hydroxyphenyl)phenylphosphine or H₂(O,O,O) = bis(3,5-di-tert-butyl-2-hydroxyphenyl)phenylphosphineoxide) and thiols (HSR; R = mesityl (Mes), 2,4,6-ⁱPr₃C₆H₂ (Tip)). The vanadium-thiolate complexes were subjected to the V/Fe/S cluster synthesis via treatment with an Fe(II) thiolate complex [(TipS)Fe]₂(¦Ì-SDmp)₂ (4, Dmp = 2,6-(mesityl)₂C₆H₃) and elemental sulfur in toluene, giving two new V/Fe/S clusters. One is an edge-bridged double-cubane-type [VFe₃S₄]-[VFe₃S₄] cluster [(O,P,O)VFe₃S₄(SDmp)(HNMe₂)]₂ (5) having face-capping tridentate (O,P,O) ligands on vanadium atoms. The other is a [VFe₃S₄-Fe] cluster [(¦Ì-O,O,O)VFe₃S₄(SDmp)(STip)Fe(¦Ì-SDmp)] (6), the core of which consists of a cubane-type [VFe₃S₄] unit and an external iron atom. The external iron is bound to an SDmp ligand and two oxygen atoms of the tridentate (O,O,O) ligand. Cluster 6 is structurally relevant to the active site of nickel-dependent CO dehydrogenase, and their common structural features include a cubane-type unit with a heterometal, one more iron atom besides the cubane unit, and a bridging ligand between the external iron and the heterometal of the cubane unit.

Ohta, Shun published the artcileSynthesis and characterization of heteroleptic iron(II) thiolate complexes with weak iron-arene interactions, Synthetic Route of 22693-41-0, the publication is Journal of Organometallic Chemistry (2007), 692(21), 4792-4799, database is CAplus.

Selective preparation and characterization of heteroleptic thiolate complexes of Fe(II) are described. The compounds were synthesized by treatment of Fe bis-amide Fe{N(SiMe₃)₂}₂ (1) with 1 equiv of terphenyl thiols HS(2,6-(aryl)₂C₆H₃) (aryl = mesityl, C₆H₃Me₂-2,6, Ph, p-tol) followed by addition of another equivalent of a different thiol. Five heteroleptic thiolate complexes were synthesized according to this pathway. Addnl., three new homoleptic thiolate complexes were also prepared by addition of 2 equiv of bulky thiols to 1. An amide-thiolate intermediate [{(Me₃Si)₂N}Fe]₂(¦Ì-SDpp)₂ (2; Dpp = 2,6-Ph₂C₆H₃) was isolated from the 1:1 reaction of 1 and HSDpp. The x-ray crystal structures of all new thiolate complexes were determined The compounds crystallize as monomers or dimers, dependent on the substituents. They consist of distorted tetrahedral or trigonal-planar Fe centers with weak interactions to the aromatic rings of the thiolate ligands. The shortest Fe-C(arene) contact is 2.272(2) ?. Stronger Fe-arene interactions appear to induce a more pyramidalized arrangement at the Fe center.

Look, Kai published the artcileFormation by S_RN1 reactions and ¹H N.M.R. properties of sterically encumbered 2,4,6-trialkylphenyl p-nitrobenzyl sulfides, Safety of 2,4,6-Triisopropylbenzenethiol, the publication is Australian Journal of Chemistry (1999), 52(11), 1077-1083, database is CAplus.

Sterically hindered p-nitrobenzylic chlorides react with the sodium salts of 2,4,6-trialkylbenzenethiols by the S_RN1 reaction to give good yields of the corresponding p-nitrobenzylic aryl sulfides. For example, the reaction of sodium 2,4,6-triisopropylbenzenethiolate with ¦Á-t-butyl-¦Á-methyl-p-nitrobenzyl chloride gives the sulfide in over 80% yield after 2 h at room temperature in Me₂SO. Only in reactions involving 2,4,6-tri-t-butylbenzenethiol are low yields or failed reactions encountered. Qual. examination of the dynamic NMR spectra of the sulfides prepared in these reactions shows that up to three restricted rotational phenomena can be identified. These are rotation about the benzylic-carbon to p-nitrophenyl ring bond, rotation about the sulfur to aromatic ring bond, and rotation about the bond joining the t-Bu group to the benzylic carbon. The last phenomenon produces the relatively rare and unusual situation wherein the t-Bu group appears as three distinct Me resonances at low temperatures

Li, Nian published the artcileA highly selective decarboxylative deuteration of carboxylic acids, Related Products of catalysis-chemistry, the publication is Chemical Science (2021), 12(15), 5505-5510, database is CAplus and MEDLINE.

A mild and practical method for precise deuteration of aliphatic carboxylic acids by synergistic photoredox and HAT catalysis was reported. The reaction delivered excellent D-incorporation (up to 99%) at predicted sites even in substrates bearing reactive C-H bonds or versatile functional groups. The use of a recirculation reactor with a peristaltic pump supports a scalable preparative ability (up to 50 mmol) under very mild reaction conditions. The practical and precise deuteration of readily available complex carboxylic acids made this protocol promising for the preparation of deuterium-labeled compounds

Guan, Zong published the artcileOrganic Synthesis with N-Heterocyclic Carbenes of Indazole: Synthesis of Benzo(thio)imidates, Benzo[d][1,3]thiazines and Quinazoline-4-thiones, Computed Properties of 22693-41-0, the publication is European Journal of Organic Chemistry (2015), 2015(21), 4710-4719, database is CAplus.

The N-heterocyclic carbenes of indazole, generated by deprotonation of indazolium salts, proved to be versatile starting materials for organic synthesis. They undergo ring-opening reactions to generate ketenimines which readily add thiols thus affording the first examples of 2-anilinobenzothioimidates. Water converts the ring-opened intermediates into functionalized 2-anilinobenzamides which can be thionated with Lawesson’s reagent and subsequently cyclized with formaldehyde and propionaldehyde, resp., to give benzo[d][1,3]thiazines and quinazoline-4-thiones. The outcome of the cyclization depends upon the thiobenzamide substitution pattern.
