operates under simple conditions to afford the corresponding arylcyclopropyl sulfides in moderate to excellent yields. The reaction tolerates substitution in ortho-, meta- and para-substitution as well as electron-donating and electron-withdrawing groups. The S-cyclopropylation of a thiophenol was also accomplished using potassium cyclopropyl trifluoroborate.
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
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 bondformation.
