Oxocarbons and Related Compounds; Part 19. 1,4-Addition-Deamination Sequence in the Reaction of Semisquaric Hydrazides with Thiols: A Novel Synthesis of Thiosquaric-S-ester Amides The reaction of semisquaric hydrazides 5a-f, with thiols 6a-j, 12,14 has been investigated. Depending upon the substitution pattern of the educts, the solvent, and the reaction temperature the S-alkyl and S-aryl thiosquarate amides 8a-m, 11a-g, 13, 15 were obtained.
