Organotitanium reagent generated from 1-t-butylthio-3-trimethylsilyl-1-propene condenses with aldehydes to give 1 -t-butylthio-(E,Z)-1,3-alkadienes in a single step via (E)-erythro-β-hydroxysilane in a highly regio- and stereoselective manner. 1,4-Dialkyl-1,3-diene is obtaind from the diene sulfide by cross coupling reaction with Grignard reagent in the presence of nickel catalyst.

The binuclear MnIVMnIV manganese complex 1 catalyzes the periodic acid oxidation of sulfides to sulfones under mild conditions. The reaction was found to be highly selective giving almost quantitative yields of the sulfones even in the presence other easily oxidized groups. Only amines were found to hinder the reaction.

Stereoselectivethioallylation of alkynes under possiblegoldredoxcatalysis was accomplished with high efficiency (as low as 0.1 % catalyst loading, up to 99 % yield) and broad substrate scope (various alkynes, inter‐ and intramolecular fashion). The gold(I) catalyst acts as both a π‐acid for alkyne activation and a redox catalyst for AuI/III coupling, whereas the sulfonium cation generated in situ
在可能的金氧化还原催化下,炔烃的立体选择性硫代烯丙基化反应效率高(催化剂负载量低至0.1%,产率高达99%),底物范围广(各种炔烃,分子间和分子内方式)。金(I)催化剂既充当炔烃活化的π-酸,又充当Au I / III偶联的氧化还原催化剂,而原位生成的sulf阳离子则起弱氧化剂的作用。这种新颖的方法为金的氧化还原催化提供了令人兴奋的系统,而无需强氧化剂。
The catalytic reactions of triethyl- and triethoxy-silane with unsaturated sulphides
di-alkenyl sulphides of the type RS(CH2)nCHCH2 (R = C2H5, CH2CH, CH2CHCH2, C3H7, n = 0, 1 and 4) by triethyl- and triethoxy-silane, catalyzed by H2PtCl6·6 H2O, (Ph3P)3RhCl and (PhCN)2PdCl2·Ph3P, has been studied. The addition of hydrosilane to the double bond of alkenylsulphide leads to a mixture of two isomeric monoadducts. The hydrosilane can cleave the CS bond of the initial sulphides giving the
