Trifluoromethylthiodediazoniation: a simple, efficient route to trifluoromethyl aryl sulfides
Abstract
Copper(I) trifluoromethanethiolate reacts with a range of diazonium salts containing electron-withdrawing groups to give the corresponding trifluoromethyl aryl sulfides in high yield; it is also possible to carry out the diazotisation and trifluoromethylthiolation in one pot directly from the anilines.
