N-(2-Alkoxycarbonylbenzenesulfenyl)benzimidazoles as Nitrogen-, Sulfur-, and Carbon-Sulfenylation Reagents
摘要:
N-(2-Alkoxycarbonylbenzenesulfenyl)benzimidazoles reacted with nucleophiles such as amides, imidates, thiols, Grignard reagents, and active methylene compounds to yield the corresponding sulfenylated products: N-acylsulfenamides, N-sulfenylimidates, disulfides, sulfides, and sulfenylated active methylene compounds, respectively.
Acylation of arenesulfenamides proceeds efficiently by using either perfluorocarboxylic anhydrides or acid chlorides in the presence of pyridine as a base at low temperatures to give N-acylarenesulfenamides. Some N-alkylcarbonyl derivatives exist with imidic acid tautomers in an aprotic solvent. (C) 2003 Elsevier Science Ltd. All rights reserved.

bidentate sulfenamide coordination through the sulfur and oxygen atoms favors the S-arylation pathway. The mild and environmentally benign catalytic conditions enable broad functional group compatibility, allowing a variety of diaryl or alkyl aryl sulfilimines to be efficiently prepared. The Chan–Lam coupling procedure could also tolerate alkenylboronic acids as coupling partners to afford alkenyl aryl
