| Abstract: | The reactions of some cyclometallated azo and imino compounds have been studied. Treatment of IrHX(PhCCHCHNC3H7)(PCy3)2] with X2 (X = Cl, Br) yields substitution products IrHX(PhCCXCHNC3H7)(PCy3)2] without rupture of the IrC bond. Treatment of IrHCl(5-CH3 · C6H3CHNCH3) (PPh3)2] with AgClO4 and then with CNC6H11 or CO (= L) leads to the formation of the complexes IrHL(5-CH3 · C6H3CHNCH3)(PPh3)2]ClO4, the metallocyclic ring remaining intact. Rupture of the metallocyclic ring is observed when PdCl(C6H4NNPh)]2 is treated under mild conditions with CNC6H11, and the insertion product PdCl(CNC6H11)2 {(CNC6H11)2C6H4NNPh} ] is obtained.Possible mechanisms for the reactions are discussed. |
