Facile lithiation of co-ordinated t-methylphosphines in bis-(2,6-dimethoxyphenyl)nickel(II) complexes
Abstract
Reactions of n-butyl-lithium with the bis-(2,6-dimethoxyphenyl)nickel(II) complexes, trans-[Ni{C6H3(OMe)2-2,6}2(PR3)2](PR3= PMe3 and PMe2Ph), in di-ethyl ether resulted in the facile lithiation at the methyl carbon in the PR3 ligands.
