M3LnPR2(C6H4X)} [M3Ln= (Ru/Os3(CO)11 or RU3(μ-dppm)(CO)9; X=NH2, NHCOPh, N=CHPh, CHO or CH=NNHAr, but not all combinations] have been prepared and their reactions studied. Predominant were H-migrations from the ary] substituent X to cluster; less facile were CC bond cleavage reactions, and PC bond cleavages were not observed. Under the conditions used, the complexes Ru3(CO)11PPh2(C6H4X-2)} were transient
M 3 L n PR 2(C 6 H 4 X)}类型的几种配合物[M 3 L n =(Ru / Os 3(CO)11或RU 3(μ-dppm)(CO)9; X =制备了NH 2,NHCOPh,N = CHPh,CHO或CH = NNHAr,但并未研究所有反应,主要是H从芳基取代基X迁移至簇;CC键断裂较不容易没有观察到反应,没有观察到PC键断裂。在所用条件下,络合物Ru 3(CO)11 PPh 2(C 6 H4 X-2)}均RU的形成瞬时中间体3(μ-H)μ-PPH 2(C 6 H ^ 4(XH)-2)}(CO)9 ; 类似的Ru 3(μ-dppm)和Os 3(μ-dppm)配合物更坚固。对于通过RU 3(CO)12和相关配合物与PPh 2 CH 2 C(O)Ph}}反应制得的簇,发现了相似的反应,其中H从配体向簇的迁移导致形成膦-烯酸酯体系。报道了配合物Os 3(CO)11
