Reactions of Cp2M (M = Ni, V) with dilithium diamido-aryl reagents; retention and oxidation of the transition metal ions†
Abstract
The reactions of dilithium 1,2-diamidobenzene, [1,2-(HN)2C6H4]Li2 (L1111H2222)Li2, and dilithium 1,8-diamidonaphthalene, [1,8-(NH)2C10H6]Li2 (L222H222)Li2, with Cp2Ni and Cp2V have been used to obtain the new complexes (L222H222)2Ni{Li(THF)2}2 (3), (L222H222)3V{Li(THF)2}3 (4) and (L1111H2222)6Ni6·{[(L1111H2222)3(L11H)3Ni6Li(THF)]2−·2[Li(THF)4]+} (5), in which retention or
