Sulfenylation of C–H Bonds for C–S Bond Formation under Metal‐Free Conditions
Sulfenylation of C–H bonds for C–S bond formation under metal-free conditions has become established as a powerful tool in organic chemistry. Various sulfenylation reagents such as thiols, disulfides, sulfinic acids, and so on have been employed for sulfenynlation reactions. In this review we mainly summarize the recent advances (2014 to the present) in this area and also discuss the mechanisms.
