Block, Eric published the artcileMercury(II) and methylmercury(II) complexes of novel sterically hindered thiolates: carbon-13 and mercury-199 NMR studies and the crystal and molecular structures of [MeHg(SC6H2-2,4,6-Pr-iso3)], [Hg(SC6H4-2-SiMe3)2], [Hg(2-SC5H3N-3-SiMe3)2], and [Hg{(2-SC6H4)2SiMe2}]2, Application of 2,4,6-Triisopropylbenzenethiol, the publication is Inorganic Chemistry (1990), 29(17), 3172-81, database is CAplus.

Several series of complexes of the types [MeHg(SR)] and [Hg(SR)2] were synthesized, where the ligands are members of new classes of sterically hindered thiolates, including (triorganosilyl)methanethiols, 2-(triorganosilyl)benzenethiols, 3-(triorganosilyl)pyridine-2-thiols, and bis(2-mercaptophenyl) derivatives Detailed 1H, 13C, and 199Hg NMR studies revealed several general trends. The 199Hg chem. shifts moved upfield in the order [MeHg(SR)] < [Hg(SCR’R”R”’)2] < [Hg(S-aryl)2] < [Hg(S-pyridyl)2]. For the [MeHg(SR)] series of complexes, 1J(Hg-C) correlates with ¦Ä(13C(methyl)) and with the type of thiolate ligand. Anomalous behavior is observed for oligomeric species. There is only a limited correlation of ¦Ä(199Hg) with steric cone angles for a subset of the complexes. The structures of 4 of these complexes, I–IV, were determined by x-ray crystallog.

Chen, Qin published the artcileSynthesis and characterization of platinum(II)-thiolate complexes. Crystal and molecular structures of cis-Pt(Ph3P)2(SC6H2-2,4,6-iPr3)Cl and cis-Pt(Ph3P)2(SC6H2-2,4,6-iPr3)2, COA of Formula: C15H24S, the publication is Inorganica Chimica Acta (1994), 216(1-2), 83-7, database is CAplus.

The reaction of cis-Pt(Ph3P)2Cl2 with 2,4,6-triisopropylbenzenethiol (HTIPT) in benzene at 65° yields yellow crystals of cis-[Pt(Ph3P)2(TIPT)Cl] (1), while the reaction of cis-Pt(Ph3P)2Cl2 and HTIPT in benzene at room temperature yields cis-[Pt(Ph3P)2(TIPT)2] (2). In contrast to the tendency of solutions of [Pt(R3P)2(SR’)2] with sterically innocent thiolates to rearrange into a complex mixture of cis and trans complexes and polynuclear materials upon exposure to air, solutions of both 1 and 2 are stable with respect to isomerization and oligomerization. Crystal data for 1·2H2O are monoclinic space group P21/c, Z = 4, R = 0.074 and for 2 they are monoclinic space group P21/n, Z = 4, R = 0.049..

Mori, Ichiro published the artcileStereoselective additions of nucleophilic alkenes to chiral thionium ions, Formula: C15H24S, the publication is Journal of Organic Chemistry (1990), 55(24), 5966-77, database is CAplus.

A convenient one-pot process has been developed for conversion of an aldehyde to an arylthionium ion which can be trapped by a nucleophilic alkene. The stereochem. of the reactions of such chiral and prochiral arylthionium ions with achiral and prochiral nucleophilic alkenes has been studied. The major adducts are those predicted by qual. application of the Cram-Felkin rule. Quant., however, the nature of the thionium aryl group has a marked effect. In reactions between prochiral thionium ions and prochiral enol silanes, good simple (anti) relative stereochem. is observed, especially with enol silane I. Mesitylthionium ions of α-chiral aldehydes react with prochiral enol silanes to give one of the four possible products in predominance. Again, however, enol silane I is found to be a superior reagent, giving II in 97% stereoisomeric purity. The α-methyl-β-arylthio ketones produced in these thionium ion reactions can be transformed by a straightforward process, which includes desulfurization, into chain compounds having anti 1,3-di-Me branches. An iterative application of this scheme can be used to prepare deoxypolypropionate structures.

An asym. oxy-Michael addition to a γ-hydroxy-α,β-unsaturated thioester via hemiacetal intermediates in the presence of Cinchona-alkaloid-thiourea-based bifunctional organocatalysts is reported. This method provides a novel enantioselective route to β-hydroxy carboxyl compounds, which in turn can be used to synthesize valuable chiral building blocks.

Ohki, Yasuhiro’s team published research in Chemistry – A European Journal in 23 | CAS: 22693-41-0

Chemistry – A European Journal published new progress about 22693-41-0. 22693-41-0 belongs to catalysis-chemistry, auxiliary class Other Functionalization Reagent, name is 2,4,6-Triisopropylbenzenethiol, and the molecular formula is C15H24S, Product Details of C15H24S.

Ohki, Yasuhiro published the artcileSynthesis and Characterization of Bioinspired [Mo2Fe2]-Hydride Cluster Complexes and Their Application in the Catalytic Silylation of N2, Product Details of C15H24S, the publication is Chemistry – A European Journal (2017), 23(53), 13240-13248, database is CAplus and MEDLINE.

The hydride-supported [Mo2Fe2] cluster complex {Cp*Mo(PMe3)}2{FeN(SiMe3)2}2(H)8 (2a; Cp*=η5-C5Me5) and its [Mo2Mn2] congener 2b were synthesized from the reactions of Cp*Mo(PMe3)(H)5 (1) with M{N(SiMe3)2}2 (M=Fe, Mn). The amide-to-thiolate ligand-exchange reactions of complex 2a with bulky thiol reagents (HSR; R=2,4,6-iPr3C6H2 (Tip), 2,6-(SiMe3)2C6H3 (Btp)) furnished the corresponding hydride-supported [Mo2Fe2](SR)2 cluster complexes. The [Mo2Fe2] clusters served as catalyst precursors for the reductive silylation of N2 and yielded â‰?5-69 equiv of N(SiMe3)3 relative to the [Mo2Fe2] clusters. Treatment of complexes 2a and b with an excess of CNtBu resulted in the formation of dinuclear Mo-Fe and Mo-Mn complexes, which indicated that the [Mo2M2] cores (M=Fe, Mn) split into two dinuclear species upon accommodation of substrates.

Reisner, Erwin published the artcileInfluence of Steric Hindrance on the Core Geometry and Sulfoxidation Chemistry of Carboxylate-rich Diiron(II) Complexes, Application In Synthesis of 22693-41-0, the publication is Inorganic Chemistry (2007), 46(24), 10229-10240, database is CAplus and MEDLINE.

The asym. terphenyl-2′-carboxylate ligand 3,5-dimethyl-1,1′:3′,1”-terphenyl-2′-carboxylate, –O2CArPh,Xyl, was prepared in high yield. This ligand facilitates the assembly of the diiron(II) complexes [Fe2(μ-O2CArTol)2(O2CArPh,Xyl)2(THF)2] [2, –O2CArTol = 2,6-di-p-tolylbenzoate], [Fe2(μ-O2CArTol)2(O2CArPh,Xyl)2(pyridine)2] (5), [Fe2(μ-O2CArPh,Xyl)2(O2CArPh,Xyl)2(THF)2] (3), and [Fe2(μ-O2CArPh,Xyl)2(O2CArPh,Xyl)2(pyridine)2] (6), all of which have a windmill geometry. The Fe-Fe distance of 3.355[10] Å in 6 is âˆ? Å shorter than that in the analog [Fe2(μ-O2CArTol)2(O2CArTol)2(pyridine)2] (4) and similar to the âˆ?.3 Å metal-metal separation at the active site of the reduced diiron(II) form of the soluble methane monooxygenase hydroxylase enzyme (MMOHred). Ortho-substituted picolyl-based ligands, 2-picSMe, 2-picSEt, 2-picStBu, 2-picSPh, 2-picSPh(Me3) (Ph(Me3) = mesityl), and 2-picSPh(iPr3) (Ph(iPr3) = 2,4,6-triisopropylphenyl), were prepared and allowed to react with [Fe2(μ-O2CAr)2(O2CAr)2(THF)2] to produce [Fe2(μ-O2CAr)3(O2CAr)(picSR)] (7–13, Ar = ArTol or ArPh,Xyl) complexes in 45-87% yields. The substrates tethered to the pyridine N-donor ligands picSR, where R = Me, Et, tBu, or Ph, coordinate to one Fe atom of the diiron(II) center by the N and S atoms to form a five-membered chelate ring. The Fe-S distance becomes elongated with increasing steric hindrance imparted by the R group. The most sterically hindered ligands, 2-picSPh(Me3) and 2-picSPh(iPr3), bind to the metal only through the pyridine N atom. The reactions of several of these complexes with dioxygen were studied, and the oxygenated products were analyzed by 1H NMR spectroscopy and GC/MS measurements following decomposition on a Chelex resin. The amount of sulfoxidation product is correlated with the Fe···S distance. The ratio of oxidized to unoxidized thioether substrate varies from 3.5, obtained upon oxygenation of the weakly coordinated 2-picSPh ligand in 10, to 1.0, obtained for the bulky 2-picSPh(iPr3) ligand in 12, for which the Fe-S distance is >4 Å. External thioether substrates were not oxidized when present in oxygenated solutions of paddlewheel and windmill diiron(II) complexes containing 1-methylimidazole or pyridine ligands, resp.
