文摘

The conformations of alkylcobalt tricarbonyltertiary phosphine complexes,ROC(O)CH₂Co(CO)₃L(L= PPh₃; R = Me, Et, n-Pr, i-Pr, s-Bu, t-Bu, c-Hex(twomodifications), CH₂Ph,(S)-{[EtOC(O)]CH(Me)},(1S,2R,5S)-menthyl,(1R,2S,5R)-menthyl; L =P(1S,2S,5R-menthyl)Ph₂, R = i-Pr), have been studied incrystallinephases by single-crystal X-ray diffraction. The geometries of the complexes are of a trigonal-bipyramidal typewith the non-carbonyl ligands in the two axial positions.We find that the (chiral) conformations of the alkylligand and the phosphine group develop concertedly.
