Investigations on organozinc compounds I. Some coordination complexes of dibutyl-, diphenyl-, and bis(pentafluorophenyl)zinc

Abstract

Dibutyl-, diphenyl-, and bis(pentafluorophenyl)zinc have been found capable of forming coordination complexes with various oxygen-, nitrogen-, phosphorus- and arsenic-containing ligands. Bidentate ligands yield 1:1 complexes, triphenylphosphine 2:1 complexes.

The influence of the organic groups attached to zinc on the stability of these complexes and the possible role of dn---dn bonding in complexes with phosphorus- and arsenic-containing ligands has been discussed.

Complexes with tetramethyl-2-tetrazene have been found to display interesting thermal behaviour.

The preparation of bis(pentafluorophenyl)zinc is reported.
