Interplay of phosphido and phosphine ligands in dinuclear ruthenium complexes: implication in the catalytic hydroformylation of ethylene
Abstract
The conversion of the diphenylphosphine complex [Ru2(CO)4(µ-O2CEt)2(PPh2H)2]1 into the diphenylphosphido complex [Ru2(CO)6(µ-PPh2)2]2 under a pressure of CO and the conversion of 2 into the ethyldiphenylphosphine complex [Ru2(CO)4(µ-O2CEt)2(PPh2Et)2]3 in the presence of ethylene and water have been studied; high-yield syntheses for the known complex 2 are also reported.
