Synthesis of Aryl Sulfides: Metal-Free C–H Sulfenylation of Electron-Rich Arenes
摘要:
A simple, efficient, and practical metal-free C-H sulfenylation of substituted electron-rich arenes has been developed. This method is highly regioselective, and the corresponding aryl sulfides were obtained in moderate to excellent yields from stable and readily accessible N-(alkylthio)- and N-(arylthio)succinimides at room temperature in the presence of TFA.

The reactions of bromonaphthalenediazonium tetrafluoro-borates (6a,b and 11a,b) with sodium benzenethiolate in DMSO give, through the preliminary formation of the corresponding diazosulfides (7a,b and 12a,b), bis(phenylthio)naphthalenes (8a,b and 13a,b) deriving from substitution of both the diazo group and the bromine. Isolated diazosulfides (7a,b and 12a,b) likewise furnish satisfactory yields of
