摘要：
The PPh3 ligands of the cluster complex [Ru3-(mu-H)(mu3, eta2-ampy)(CO)7(PPh3)2] (1) (ampy = 2-amino-6-methylpyridinate) undergo carbon-phosphorus bond scission on reaction with hydrogen (110-degrees-C, 1 atm) or diphenylacetylene (110-degrees-C) to give [Ru3(mu3,eta2-ampy)-m-PPh2)2(mu-Ph)(CO)6] (2) or [RU3 (mu3,eta2-ampy) (mu-PPh2)-{mu,eta1:eta2-PhC=C(H)Ph}(Ph) (CO)5(PPh3)] (3), which have been characterized by X-ray crystallography. Complex 2 represents the first example in ruthenium chemistry of a bridging eta1-phenyl derivative.
