Abstract
The conformations of alkylcobalt tricarbonyl tertiary phosphine completes, ROC(O)CH2Co(CO)(3)L(L = PPh(3); R = Me, Et, n-Pr, i-Pr, s-Bu, t-Bu, c-Hex (two modifications), CH(2)Ph, (S)-{[EtOC(O)/CH(Me)}, (1S,2R,5S)-menthyl, (1R,2S,5R)-menthyl; L = P(1S,2S,5R-menthyl)Ph(2), R = i-Pr), have been studied in crystalline phases by single-crystal X-ray diffraction. The geometries of the complexes are of a trigonal-bipyramidal type with the non-carbonyl ligands in the two axial positions. We find that the (chiral) conformations of the alkyl Ligand and the phosphine group develop concertedly.Pubblicazioni consigliate
