involving the intermediary formation of the sulfonium species 11 by nucleophilic attack of sulfide toward the iodine(III) atom of 2 is proposed for the oxidation in acetonitrile-water in the presence and the absence of BF(3). Et(2)O. On the other hand, the oxidation of sulfoxides in dichloromethane probably proceeds by a radical process, which involves the decomposition at room temperature of 2 via
carried out under transition-metal-free conditions, showing yields of asymmetric sulfides higher than 80%. Tertiary alkyl halides and aryl halides do not react with thiourea under formation of the corresponding isothiouroniumsalts; however, 5-bromopyrimidine and 2-bromopyrimidine lead to yields of 79.2% and 87.6%, respectively. This method is of significant importance from the both environmental and economic
