Abstract

The cobalt(I)-catalyzed cycloaddition of alkynyl sulfides with1,3-dienes can be realized at ambient temperatures. In combinationwith a mild oxidation step various polysubstituted and functionaliseddiaryl sulfides can be synthesized in good overall yields.

Small amounts of reduction products,such as alkenyl sulfides, were detected by GC-MS analysis.
