摘要

Main observation and conclusion Based on the redox reactions of Togni-II reagent and thiols, a thiol-tuned selective functionalization of unactivated olefins was disclosed. In combination with aryl thiols, stoichiometric amount of Togni-II reagent prompted a hydrotrifluoromethylation of alkenes, in which, aryl thiols played as reductant and hydrogen source; while by utilization of alkyl thiols, catalytic amount of Togni-II reagent initiated thiol-ene and thiol-yne reactions. The reported applications are characterized by their operational simplicity and wide functional group tolerance.
