Organozinc Compound - Organozincates


The first ever organozinc ate complex (organozincate) was discovered in 1858 by James Alfred Wanklyn, an assistant to Frankland and concerned the reaction of elemental sodium with diethylzinc:

2Na + 3 Et2Zn -> 2Et3Zn-Na+ + Zn

In 2007 it was reported that by tweaking the reaction conditions the zincate proceeds to react to sodium hydridoethylzincate(II) (with hydrogen atoms as bridging ligands) as a result of beta-hydride elimination of one of the ethyl groups:
