摘要：

Reaction of 2,6-bis-((BuNHCH2)-Bu-t)(2)NC5H3 ("N(2)py") with RuCl2(PPh3)(3) gives two isomers of Ru(N(2)py)Cl-2(PPh3), 5, while reaction with RuCl2(DMSO)(4) (DMSO = Me2SO) gives isomerically pure Ru(N(2)py)Cl-2(DMSO), whose structure is reported. The PPh3 of 5 can be replaced by CO, P(OPh)(3), or pyridine. The chlorides in Ru(N(2)py)Cl-2(CO) can both be replaced by F3CSO3-. Isomer structure preferences are discussed, and the reaction of Ru(N(2)py)Cl-2(pyridine) with Oz gives apparent oxidation of N(2)py to give the diimine.
