Abstract
The chiral complex RuCl2(eta(6)-p-cymene)[(R)(-)-sec-butylamine], 1, has been synthesized. The preferential conformation of 1 in solution, determined by H-1 NMR, is very close to that found by X-ray analysis in the solid state of the racemic compound RuCl2(eta(6)-p-cymene)[(R,S)-sec-butylamine], 1'. On the H-1 NMR time scale, the rotation of the p-cymene is restricted at room temperature because of steric inter actions with the amine ligand.File in questo prodotto:
