A general and efficient method for the preparation of unsymmetrical bidentate P,N and P,S ligands
摘要:
A general and efficient preparation of chiral and achiral P,N and P,S ligands is described where ligands are prepared by reacting a variety of 2- or alpha-lithio N- or S-heterocycles and a lithiated phosphine with 1,2-cyclic sulfates. (c) 2006 Elsevier Ltd. All rights reserved.
