Addition of CO to Ru(C6H4NO2-4)Cl(CO)(P-Ph3) 2 (1) gives Ru(C6H4NO2-4)Cl(CO)2(PPh3) 2 (2), which upon reduction with Zn/HCl followed by treatment with base produces the η2-acyl complex Ru(η2-C[O]C6H4NH 2-4)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 formation of [Ru-(C6H4NH3-4)Cl(CO)2(PPh 3)2]BF4 (4). The process is reversible, and treatment of 4 with DBU returns 3.
