Iodine-Mediated Thiolation of Substituted Naphthols/Naphthylamines and Arylsulfonyl Hydrazides via C(sp2)–H Bond Functionalization
摘要:
A direct method has been developed for iodine-mediated thiolation of naphthols/naphthylamines and arylsulfonyl hydrazides through the formation of C-S bond and cleavage of S-N/S-O bonds. In this transformation, a range of valuable thioethers are easily achieved in moderate to good yields.
An aerobic metal-free, visible-light-induced regioselective thiolation of phenols with thiophenols is reported. The cross-coupling protocol exhibits great functional group tolerance and high regioselectivity. Mechanistic studies reveal that the disulfide radical cation plays a crucial role in the visible-light catalysis of aerobic thiolation. Simply controlling the equivalent ratio of substrates enables

A simple, efficient and green method for the direct thiolation of aromaticcompounds using commercially available sulfonyl chlorides as the sulfur source was developed under metal- and solvent-free conditions. The C–S bond was constructed via direct C–H functionalization of diverse aromaticcompounds under an oxygen atmosphere. In this process, various diaryl sulfides were synthesized in moderate to
