摘要：

New chiral cationic phosphinite ligands based on ephedrine or valinol skeletons, and corresponding zwitterionic hydridotricarbonylfenate complexes are described. IR data indicate an unusual cis-H-Fe-P arrangement in these complexes, and NMR studies show an unusual variation of (2)J(PH) with temperature and solvent. The possibility that both these rare features are dictated by a stabilizing back folding of the [NMeR2](+) terminus onto the [FeH](-) center is discussed. (C) 1998 Elsevier Science S.A.
