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.
A method for producing a polydiene, the method comprising the steps of (i) forming an active catalyst by combining a lanthanide-containing compound, an alkylating agent, and a halogen source in the substantial absence of an organosulfide; and (ii) polymerizing conjugated diene monomer in the presence of the active catalyst and an organosulfide.
