An indium-catalyzed reaction of lactones and a disilathiane leading to thiolactones is described. The direct synthesis of thiolactones from lactones with an appropriate sulfur source is one of the most attractive approaches in organic and pharmaceutical chemistry. In this context, we found an indium-catalyzed direct conversion of lactones into thiolactones in the presence of elemental sulfur and a hydrosilane via formation of the disilathiane in situ. On the basis of the previous reaction, the application utilizing the disilathiane as a sulfur source was performed herein for the efficient synthesis of a variety of thiolactone derivatives from lactones by an indium catalyst.
The first isolation and structural analysis of chalcogenocarboxylato samarium complexes, [(RCOS)3Sm(thf)2] and [Na(thf)4] [Sm(RCSS)4]; the alkali metal salt-like reaction and the insertion reaction of imine to the Sm-S bond

The first chalcogenocarboxylato lanthanid complexes, [(RCOS)3Sm(thf)2] and [Na(thf)4][Sm(RCSS)4](R=4-MeC6H4) were isolated and characterized crystallographically. They exhibit an alkali metal salt-like reaction such as S-esterification and an insertion reaction of C=N to the Sm-S bond.

The reaction of sodium or caesium dithiocarboxylates with diphenylthiophosphinic and diphenylselenophosphinic chlorides gives purple thioacyl diphenylthiophosphinoyl 5 and dark green thioacyl diphenylselenophosphinoyl sulfides 6, which are useful thioacylating reagents under mild reaction conditions.Thioacyl diphenylphosphino sulfides 22, which can be obtained by the similar method using diphenylphosphinous chlorides, react with methanol to yield the corresponding methyl dithiocarboxylates 15, while the reactions of 22 with N-chlorosuccinimide lead to hitherto unknown N-(thioacetylthio)succinimides 28.

Raney Nickel desulphuration of some bisthioaroyl disulphides (I), and lead salts (II) and esters (III) of dithioacids with W-2A, W-2B and W-2C catalysts has been investigated.In some cases dimorphic products are obtained.
Aromatic Substitution. 46. Methyl (Ethyl) Thio(Dithio)carboxylation of Aromatics with S-Methyl (S-Ethyl) Thiocarboxonium and Dithiocarboxonium Fluoroantimonates

S-Methyl(S-ethyl)thio(dithio)carboxinium ions were prepared by reacting methyl(ethyl) fluoride-antimony pentafluoride with carbonyl sulfide (carbon disulfide) and studied with 1H and 13C NMR spectroscopy.The ions were subsequently used in the novel carboxylation reaction of arenes to S-methyl (S-ethyl) thio(dithio)benzoates.The method was also found to be adaptable to the carboxylation of polystyrene to poly(styrenecarboxylic acid) without degradation of the polymer backbone.
