The reduction of carbon-carbon multiple bonds in alkynes and olefins supported on a polystyrene resin has been investigated. Homogeneous catalysis by titanocene reagents is effective for the stereoselective preparation of cis-olefins from diarylacetylenes, while the use of copper(I) hydride reagents is effective for the reduction of alpha,beta-unsaturated ketones.
研究了在聚苯乙烯树脂上负载的炔烃和烯烃中碳-碳多重键的减少。二芳基乙炔通过茂金属试剂的均相催化可立体选择性地制备顺式烯烃,而使用铜(I)氢化物试剂则可有效还原α,β-不饱和酮。
