A series of Se-aryl carboselenothioates 3 (RCSSeAr, R=alkyl, aryl) were synthesized and characterized from the reaction of bis(thioacyl) sulfides 1 with sodium areneselenolates.The thionselenolesters 3 are stable (liquid or crystals) both thermally and to moisture.Reactions of 3 with aliphatic primary and secondary amines gave the corresponding ammonium carbodithioates 8 together with diphenyl diselenide 7.In contrast, treatment with aromatic amines or sodium alcoholates afforded the corresponding thioamides or O-alkyl or O-aryl thionoesters in good yields.The oxidation of 3 with m-chloroperbenzoic acid gave the corresponding sulfides 12 and acyl arylseleno sulfides 13 which are formed by a rearrangement of the ArSe group to the thiocarbonyl sulfur atom.

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

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.
