An efficient and convenient strategy for the preparation of diaryl sulfides via a Fe‐promoted direct sulfuracylation of 2‐naphthylamine using thioesters as bifunctional reagents is described. This synthetic strategy features high chemoselectivity, good substrate scope and functional group tolerance.

A formalcarbeneinsertion into C(O)–S bonds to access α-quaternary pyridines was achieved via a rhodium(II)-catalyzed in situ formation of sulfonium ylides from pyridotriazoles with thioesters followed by acyl group migration. This protocol has enabled an efficient denitrogenative gem-acylthiolation of pyridotriazoles to incorporate an acyl, pyridyl, and sulfur-substituted quaternary carbon center
通过铑( II )催化从吡啶三唑与硫酯原位形成锍叶立德,随后酰基迁移,实现了正式的卡宾插入C(O)-S键以接近α-季吡啶。该协议使吡啶三唑的高效脱氮宝石-酰基硫醇化能够结合酰基、吡啶基和硫取代的季碳中心,具有高选择性、广泛的底物范围和良好的官能团耐受性。

stimuli used to promote a chemical reaction, photocatalysis possesses a unique one—light. Photons are traceless reagents that provide an exclusive opportunity to alter chemoselectivity of the photocatalytic reaction varying the color of incident light. This strategy may be implemented by using a sensitizer capable to activate a specific reaction pathway depending on the excitation light. Herein, we
