Cross-metathesis reactions of α,β-unsaturated sulfones and sulfoxides in the presence of molybdenum and ruthenium pre-catalysts 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
测试了在钼和钌预催化剂存在下α,β-不饱和砜和亚砜的交叉复分解反应。通过使用“第二代”钌催化剂1c - h,在官能化的末端烯烃和乙烯基砜之间实现了选择性的复分解反应,而高活性的Schrock催化剂1b是与乙烯基砜不相容的官能团。交叉复分解产物以良好的产率分离并具有优异的(E)选择性。但是,钼和钌基络合物均与α,β-和β,γ-不饱和亚砜不相容。
