Abstract
Addition of CO to Ru(C6H4NO2-4)Cl(CO)(P-Ph-3)(2) (I) gives Ru(C5H4NO2- 4)Cl(CO)(2)(PPh3)(2) (2), which upon reduction with Zn/HCL followed by treatment with base produces the eta(2)-acyl complex Ru(eta(2)-C[O]C6 H4NH2-4)Cl(CO)(PPh3)(2) (3), the molecular structure of which has been determined. Treatment of 3 with HBF4 protonates the amino substituent and brings about a reverse migratory insertion reaction with the form ation of [Ru-(C6H4NH3-4)Cl(Co)(2)(PPh3)(2)]BF4 (4). The process is rev ersible, and treatment of 4 with DBU returns 3.
