摘要
A DFT study was carried out to investigate the reaction mechanisms of a model mu-benzoquinone diruthenium complex {CpRu(mu-H)}(2)(mu-eta(2):eta(2)-C6H4O2), derived from the experimental compound {Cp*Ru(mu-H)}(2)(mu-eta(2):eta(2)-C6H3RO2) (R = H or R = Me, Cp* = eta(5)-C5Me5), with acetylene both in aprotic and protic solvents. Results of calculations show that the influence of the solvent methanol on the reaction is mainly on the step of acetylene coordination. Enhanced hydrogen bonding is the reason for acceleration of the reaction in protic solvent, which is supported by NBO charge analysis.
