N-(2-Alkoxycarbonylbenzenesulfenyl)benzimidazoles as Nitrogen-, Sulfur-, and Carbon-Sulfenylation Reagents

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.
