MgII (RMgX) remain unknown until today. The same is true for the reaction of bulk magnesium with Group 15 halide compounds that give biradicaloid species. We investigate the reduction of P−Cl bonds with solutions of [MgIBr(NnBu3)]2 (1). The phosphanes [ClP(μ‐NTer)]2 (2) and (Me3Si)2N‐PCl2 (3), were chosen as they had successfully been reduced by Mg metal before. Furthermore, reactions of both 1 and
