Isolation of Bis- and Mono-Cyclometallated Ru-IMes complexes upon reaction of [Ru(PPh3)3HCl], IMes and ZnMe2

Addition of an excess of ZnMe2 to a mixture of [Ru(PPh3)3HCl] and IMes (IMes=1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene) yields the bis-cyclometallated complex, [Ru(IMes)“(PPh3)2] 2, together with the mono-cyclometallated, Ru−Zn heterobimetallic complex [Ru(IMes)′(PPh3)2(ZnMe)] 3. Treatment...
