摘要:
Triruthenium dodecacarbonyl-Ru-3(CO)(12) based diphenylarsino methane-triphenyl phosphine derivatives, such as Ru-3(CO)(9)-dpam-tris (methyl phenyl) phosphine (1), Ru-3(CO)(9)-dpam-tris (methoxy phenyl) phosphine (2), and Ru-3(CO)(9)-dpam-tris (fluro phenyl) phosphine (3) are synthesized by two step modified method. The catalytic hydrogenation of cyclohexene, styrene, and phenyl acetylene, on above mentioned Ru-based organometallic catalysts, has been studied under high pressure hydrogen atmosphere. The high pressure hydrogenation of cyclohexene and phenyl acetylene on Complex (1-3), showed good catalytic activity under pressurized condition. Hydrogenation of cyclohexene on Complex (3) showed better (50-65%) conversion in the presence of toluene than hexane solvent. The effect of temperature, role of solvent, and pressure conditions have also been studied.
