A mixed bases mediated protocol is developed to synthesize thioamides from N-aryl or N-alkylamide, aldehyde and elemental sulfur in water. This reaction requires no addition of external oxidant and avoids large excess of amides. Various functional groups

Bis(thioacyl) tri- 1 and tetrasulfides 2 have been prepared by the reaction of dithiocarboxylic acids with sulfur- or disulfur dichloride.The crystalline aromatic bis(thioacyl) sulfides (1, 2, R = aromatic) are stable towards heat and moisture.The n->?su

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.

A number of selenium- 2 and tellurium bis(dithiocarboxylates) 3 have been prepared by the reaction of piperidinium or sodium dithiocarboxylates 1 with sodium seleno- and telluropentathionates.The orange or red products are stable towards heat and moisture

Reaction of dithioic acids with dicyclohexylcarbodiimide has been found to give the corresponding bis(thioacyl) sulfides 1 in good yield, which are very useful thioacylating reagents under mild reaction conditions.Most of the aromatic thioanhydrides (1, R = aromatic) are fairly stable green crystals at room temperature, but the aliphatic ones (1, R = aliphatic) are unstable purple oils which dimerize at room temperature to give the dithietanes 5.The reactions with nucleophiles are discussed.

It has been found that the reaction of diphenylmercury with an equimolar amount of thio- or dithio acids gave the corresponding phenylmercury thio- (1) or dithiocarboxylates (2), quantitatively, which further react with thio- or dithio acids to give mercury bis(thio-) (3) or bis(dithiocarboxylates) (4).The phenylmercury dithio salts (2) were found to be the very useful thioacylating agents for primary and secondary amines.The reaction of mercury bis(thiocarboxylates) (3) with dithiocarboxylic acids gave the unsymmetrical thio- and dithiocarboxylic acid mercury salts (5) in good yield. - Keywords: Phenylmercury Thiocarboxylates
