Enhanced preparation of aryl and heteryl sulfur pentafluorides using mercury (II) oxide - hydrogen fluoride media as a fluorinating reagent
We developed enhanced method for low temperature and good yield preparation of aryl and heteryl sulfur pentafluorides from chlorotetrafluorides using mercury oxide - hydrogen fluoride and mercury oxide - pyridinium poly(hydrogen fluoride) media as the fluorinating reagents.

OXIDATION OF 2-MERCAPTOBENZOHETERAZOLES BY DIMETHYLDIOXIRANE. A NEW METHOD FOR A SYNTHESIS OF C-2 SUBSTITUTED BENZIMIDAZOLE, BENZOXAZOLE, AND BENZOTHIAZOLE DERIVATIVES
New and efficient reactions in which 2-mercaptobenzoheterazoles are selectively converted by dimethyldioxirane, under mild experimental conditions, to several C-2 substituted benzoimidazole, benzoxazole, and benzothiazole derivatives are reported.
