【Abstract】 Treatment of [\{\}\+\{Me\}CnRuCl(dppe)](O\-3SCF\-3) with AgO\-3SCF\-3 in CD\-2Cl\-2 in the presence of H\-2 pressure produces the dicationic complex[\{\}\+\{Me\}CnRu(H\-2)(dppe)](O\-3SCF\-3)\-2. This ruthenium dihydrogen complex can catalyze ionic hydrogenation of some olefins. In situ high\|pressure NMR monitoring of the catalytic reaction shows that the catalytic reaction is likely initiated by proton transfer reaction from the dihydrogen complex to olefin to form carbonium ion.更多还原
