Crystal Structure Characterization and Catalytic Application of Novel Route Prepared Ru₃(CO)₉ DPAM (Diphenyl Arsino Methane)-tri Phenyl Phosphine Derivatives

Abstract

Triruthenium dodecacarbonyl-Ru₃(CO)₁₂ based diphenylarsino methane-triphenyl phosphine derivatives, such as Ru₃(CO)₉-dpam-tris (methyl phenyl) phosphine (1), Ru₃(CO)₉-dpam-tris (methoxy phenyl) phosphine (2), and Ru₃(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.
