摘要：

Reaction of the ketophosphine Ph2PCH2C(O)Ph (L) with [Ru3(CO)12] intetrahydrofuran in the presence of Me3NO affords [Ru3(CO)9L3] which reacts with I2 to give [{Ru(mu-I)[Ph2PCH...C(...O)Ph](CO)2}2]. The iodide bridges are readily cleaved by PEt3 or L, affording the mononuclear, phosphino enolate complexes [RuI{Ph2CH...C(...O)Ph}(CO)2L'] [L' = PEt3 or Ph2PCH2C(O)Ph] in which the P atoms are trans to each other. The crystal structure of [{Ru(mu-Cl)[Ph2PCH...C(...O)Ph](CO)2}2] which forms slowly in CH2Cl2 solutions of [Ru3(CO)10L2] is determined.
