摘要：

Allylrhodium complexes [Rh(eta-3-2-RC3H4(PPri3)2,]2,3, which are prepared from [RhCl(PPri3)2]n 1 and allyl Grignard reagents, react with R'CO2H (R' = Me, CF3) to give [Rh(eta-2-O2CR')(PPri3)2] 4,5 but with alk-1-ynes RC = CH (R = C6H5, Me, H) to give the alkynyl(vinylidene) compounds trans-[Rh(C = CR)(= C = CHR)(PPri3)2] 8-10; in the presence of pyridine (py) the octahedral bis(alkynyl)hydrido derivatives [RhH(C = CR)2(py)(PPri3)2] 11-13 are obtained.
