We report a general protocol for the light-driven isomerization of cyclic aliphatic alcs. to linear carbonyl compounds These reactions proceed via proton-coupled electron-transfer activation of alc. O-H bonds followed by subsequent C-C ¦Â-scission of the resulting alkoxy radical intermediates. In many cases, these redox-neutral isomerizations proceed in opposition to a significant energetic gradient, yielding products that are less thermodynamically stable than the starting materials. A mechanism is presented to rationalize this out-of-equilibrium behavior that may serve as a model for the design of other contrathermodynamic transformations driven by excited-state redox events.

The N,O chelate ligands acetyl- and benzoyl-pyridine (L) react with ZnCl₂ to form 5- and 6-coordinate complexes of the compositions L₂ZnCl₂ and [L₂ZnCl]⁺. The Zn pentafluorothiophenolate and 2,4,6-triisopropylthiophenolate, however, yield tetrahedral complexes of composition L?Zn(SR)₂. These are structural models of the Zn(NOS₂) bonding situation during aldehyde attachment in the active center of the enzyme alc. dehydrogenase.

The reaction of ZnEt₂ with 2,4,6-triisopropylthiophenol (HSR^*) and N-methyl-2-hydroxymethylimidazole (ImCH₂OH) in MeOH yields the complex Zn₄(SR^*)₄(ImCH₂O)₃(OMe) with terminal SR^* and bridging ImCH₂O and MeO ligands.

Alfie, Rachel J. published the artcileA kinetically controlled direct aldol addition of ¦Á-chloro thioesters via soft enolization, Category: catalysis-chemistry, the publication is Tetrahedron Letters (2017), 58(3), 185-189, database is CAplus.

¦Á-Chloro thioesters such as ClCH₂COSR (R = 2,4,6-i-Pr₃C₆H₂)(I) underwent diastereoselective aldol additions to aldehydes R¹CHO [R¹ = 2-naphthyl, Ph, t-Bu, cyclohexyl, i-Pr, PhCH₂CH₂, Me(CH₂)₆] in the presence of MgBr₂¡¤OEt₂ and i-Pr₂NEt in CH₂Cl₂ at -78¡ã to give the syn-aldol adducts II [R¹ = 2-naphthyl, Ph, t-Bu, cyclohexyl, i-Pr, PhCH₂CH₂, Me(CH₂)₆] as the major products in 40-80% yields and in 2:1-11:1 dr. Both enolizable and nonenolizable aldehydes underwent chemo- and stereoselective aldol addition under these conditions. At -78¡ã, the reactions are kinetically controlled, as shown by the lack of aldehyde exchange when p-tolualdehyde and an aldol adduct were submitted to the reaction conditions at -78¡ã. Aldol addition of I to (S)-i-PrCH(OTBDMS)CHO (TBDMS = tert-butyldimethylsilyl) at either -78¡ã or 24¡ã yielded III (R² = COSR) as a single diastereomer. The structure of III (R² = HOCH₂) was determined by X-ray crystallog.

The [8Fe-7S] core of the P-clusters in nitrogenases is unique among the known [Fe-S] clusters which are essential to electron-transfer processes in nature. The [8Fe-7S] cluster was thought unstable and to exist only in protein environments. This unusual [8Fe-7S] structure can be self-assembled from the reaction of Fe(II) bis-amide, tetramethylthiourea, 2,4,6-triisopropylbenzenethiol, and elemental sulfur in a specific mole ratio. The structure of the complex isolated therefrom, [{N(TMS)₂}{SC(NMe₂)₂}Fe₄S₃]₂(¦Ì₆-S){¦Ì-N(TMS)}₂¡¤C₇H₈, closely resembles that of the reduced form (P^N) of the P-clusters, while the 6Fe(II)2Fe(III) oxidation state was manifested by the Mossbauer study.

In toluene, bis(pentafluorophenyl)cadmium(II) and thiols RSH (R = Bu^t, 2,4,6-Prⁱ₃C₆H₂, 2,4,6-Bu^t₃C₆H₂) react to give soluble pentafluorophenyl cadmium thiolates [{Cd(C₆F₅)(SR)}_n].

The structure of 1.0.5 C₆H₅CH₃ was determined by x-ray crystallog. 1 Is a cubane-type complex with a {Cd₄(¦Ì₃-SBu^t)₄}⁴⁺ core. Each Cd atom is coordinated by three bridging thiolato ligands and one terminal C₆F₅ group (Cd-S 2.62 ?, Cd-C 2.15 ? (mean values)). The central C atoms of the Bu^tS^– ligands of 1 show a remarkable low-field shift of their ¹³C NMR resonance (12.3 ppm relative to the value of the free thiol). A characteristic spectral feature of {Cd(C₆F₅)}⁺ complexes is the large value of the coupling constant ²J(¹⁹F,¹³C) of the ipso-C atom (1, 2: 68 Hz; 3: 67 Hz). The complexes [Cd(C₆F₅)(SR) + H]⁺, [Cd(SR)₂+H]⁺, and [Cd₂(SR)₃]⁺ were identified in the CI mass spectra (iso-butane) of 2 and 3.

An approach to synthesize ¦Á-chiral bicyclo[1.1.1]pentanes I (R = Me, Bn, thiophen-2-yl, etc.) (BCPs) involving the direct, asym. addition of simple aldehydes RCH₂CHO to [1.1.1]propellane, the predominant BCP precursor was described. This is achieved by combining a photocatalyst and an organocatalyst to generate a chiral ¦Á-iminyl radical cation intermediate, which installs a stereocenter simultaneously with ring-opening of [1.1.1]propellane. The reaction proceeds under mild conditions, displays broad scope, and provides an array of ¦Á-chiral BCPs I in high yield and enantioselectivity. They also present a theor. model for stereoinduction in this mode of photoredox organocatalysis.

Sb(III) and Bi(III) complexes of sterically demanding arenechalcogenolato ligands, M(EC₆H₂R’₃-2,4,6)₃ (E = S or Se; M = Sb or Bi; R’ = Me, Prⁱ or Bu^t) were prepared by either protolysis of the amides M[N(SiMe₃)₂]₃ with arenechalcogenols, or from MCl₃ by halide exchange (M = Bi or Sb). The complexes are monomeric in the solid state and sublime readily. The crystal structure of Sb(SC₆H₂Prⁱ₃-2,4,6)₃ was determined by x-ray diffraction. The compound possesses a trigonal-pyramidal geometry, with Sb-S distances of 2.418(2)-2.438(2) ? and S-Sb-S angles of 94.69(7)-98.29(8)¡ã. Preliminary x-ray results on Bi(SeC₆H₂Prⁱ₃-2,4,6)₃ showed that the compounds of Sb and Bi are isostructural. Thermolytic decomposition of some of the compounds was carried out in the solid state. Compounds with R’ = Me or Prⁱ undergo reductive elimination to give elemental Bi or Sb, whereas the bulky selenolates M(SeC₆H₂Bu^t₃-2,4,6)₃ afford M₂Se₃.

The effects of Lewis acid, solvent and orthothio substituent have been examined with regard to intramol. electrophilic aromatic substitution with bisthiocarbocations. A suspension of silver trifluoromethanesulfonate in dichloromethane, creating bis(arylthio)carbocations, was found to be the most effective for annulation of six-membered rings. E.g., o-phenylene trithiocarbonate was condensed with 3-MeOC₆H₄(CH₂)₃I to give 2-[3-(3-methoxyphenyl)propyl]-2-methylthio-1,3-benzodithiole which was subject to intramol. aromatic substitution to give 6-methoxy-1-tetralone.
