摘要：

Reaction of [OsH((eta)2-H-2){(eta)2-C,C-kappa(1)-N-(CH2=CH-o -C5H4N)} (P-i Pr-3)(2)]BF4 with benzophenone affords [OsH2{kappa(2)-C,O-C6H4C(O)Ph}{kappa-C-(HNC5H3Et)}(P-i Pr-3)(2)]BF4 as a result of the orthometalation of the ketone, the hydrogenation of the vinyl substituent of the pyridine, and its subsequent tautomerization. In acetonitrile, the ketone is released and complex [OsH{kappa-C-(HNC5H3Et)}(NCCH3) (P-i Pr-3)(2)]BF4 is formed.
