laser (308 nm) irradiation of RhH(CO)(PPh3)3 accelerates the homogeneous hydrogenation of olefins under mild conditions. Significantly enhanced dark reactions were observed after periods of laser irradiation. These demonstrate the generation of a highly active catalytic species. Furthermore, the apparent quantum yield of the reaction has been estimated to be larger than unity (2.4) under appropriate conditions
用XeCl准分子激光(308 nm)辐射RhH(CO)(PPh 3)3可以在温和条件下加速烯烃的均匀氢化。激光照射一段时间后,观察到暗反应显着增强。这些证明了高活性催化物质的产生。此外,据估计,在适当条件下,该反应的表观量子产率大于一(2.4)。还观察到XeCl准分子激光诱导的与其他催化剂RhCl(PPh 3)3以及IrCl(CO)(PPh 3)2的均相氢化的加速。
