✦ Synopsis

Cross-metathesis reactions of a,b-unsaturated sulfones and sulfoxides in the presence of molybdenum and ruthenium precatalysts were tested. A selective metahesis reaction was achieved between functionalized terminal olefins and vinyl sulfones by using the 'second generation' ruthenium catalysts 1c-h while the highly active Schrock catalyst 1b was found to be functional group incompatible with vinyl sulfones. The cross-metathesis products were isolated in good yields with an excellent (E)-selectivity. Both the molybdenum and ruthenium-based complexes were, however, incompatible with a,band b,g-unsaturated sulfoxides.
