Unsubstituted phenoxo-derivatives of copper(II) and p-benzoquinone adducts of copper(I) chloride and bromide

Abstract

The reaction of [CuCl₂L][L = 2,2′-bipyridyl (bipy) or ethylenediamine (en)] with sodium phenoxide in tetrahydrofuran yields the extremely moisture-sensitive diphenoxo-derivatives [Cu(OPh)₂(bipy)](1) and [Cu(OPh)₂(en)]·PhOH (2). The reaction of CuX (X = Cl or Br) with p-benzoquinone in pyridine gives the diamagnetic adducts [CuX(py)]₂·C₆H₄O₂(3); i.r. data suggest that (3) are olefin complexes.
