First use of an organobismuth reagent in C(sp3)–S bond formation: Access to aryl cyclopropyl sulfides via copper-catalyzed S-cyclopropylation of thiophenols using tricyclopropylbismuth
The direct S-cyclopropylation of thiophenols using tricyclopropylbismuth is reported. The reaction is catalyzed by copper(II) acetate and operates under mild conditions to afford the corresponding aryl cyclopropyl sulfides in moderate to good yields. This reaction represents the first use of an organobismuth reagent in C(sp3)–S bond formation.
