Notes. On the synthesis of dimethylphenylphosphine complexes of manganese(II) halides

Abstract

The preparation of complexes of the formula MnX₂(PMe₂Ph)(X = Cl, Br, I, or NCS) is described in detail since it has been the subject of controversy. The identity of the compounds was established by a combination of chemical analysis and effective separation from unreacted tertiary phosphine. Notes on the analogous tri-n-propylphosphine complexes are included. Some observations on the reactions with dioxygen are given.
