摘要

Interaction of thiourea and substituted thioureas with trifluoromethanesulfonic acid anhydride in methylene chloride results in stable dication disulfide salts (R2N) 2+ CSSC+(NR2) 1-2CF3S03-. These results indicate that triflic anhydride is acting as an oxidizing agent toward thioureas. The most likely mechanism for the formation of these dication disulfides is an ionic pathway with initial formation of a monocation which is ...
