sulfinate intermediate. In situ conversion of the sulfinate to a sulfinate silyl ester, using TMS-Cl (trimethylsilylchloride), generates a second electrophile, allowing addition of a second organometallic reagent. Organolithium or Grignard reagents can be employed, delivering sulfoxides in good to excellent yields.

The new metal-free cross-coupling of carboxylic acids and sulfinates provides a direct and modular access to sulfoxides by a photocatalytic process that has unveiled the unexplored chemoselective radicalophilic reactivity of intermediate sulfinyl sulfones and enabled the conjunctive coupling of two carboxylic acids, revealing broad new chemical space accessible by the merger of the two coupling partner

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 a sulfone, a sulfoxide, and a phosphine oxide; and (ii) polymerizing conjugated diene monomer in the presence of the active catalyst and a polymerization modulator selected from the group consisting of a sulfone, a sulfoxide, and a phosphine oxide.
