Reactions of Resin-Bound Triazenes with Dithianylium Tetrafluoroborates: Efficient Synthesis of α-Azo Ketene Dithioacetals and Related Hydrazones

“…They can be e.g. oxidized enantioselectively to their bissulfoxides, 6 fluorinated via oxidative difluorodesulfuration, 7 can be derived by C−S bond cleavage, or converted into diverse heterocycles. 8 In addition to various well-known transformations of the α-position, the reaction of the versatile dithiane moiety with azo-building blocks has been shown to yield α-azo ketene dithioacetals recently.…”
