Abstract

Allylrhodium complexes [Rh(η3-2-RC3H4(PPri3)2]2,3, which are prepared from [RhCl(PPri3)2]n1 and allyl Grignard reagents, react with R'CO2H (R′= Me, CF3) to give [Rh(η2-O2CR′)(PPri3)2]4,5 but with alk-1-ynes RC[triple bond, length half m-dash]CH (R = C6H5, Me, H) to give the alkynyl(vinylidene) compounds trans-[Rh(C[triple bond, length half m-dash]CR)([double bond, length half m-dash]C[double bond, length half m-dash]CHR)(PPri3)2]8-10; in the presence of pyridine (py) the octahedral bis(alkynyl)hydrido derivatives [RhH(C[triple bond, length half m-dash]CR)2(py)(PPri3)2]11-13 are obtained.
