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 ...

The first productive reactions of a characterized metallacyclobutene complex with alkenes are reported. Thus, the metallacyclobutene complex (η5-C5H5)(PPh3)Co[κ2-(C,C)-C(SO2Ph)═C(Si(CH3)3)CH(CO2CH2CH3 ...
