Phosphide coupling in the reaction of Sn(NMe2)2 with MesPHLi; synthesis and structure of the Sn(ii) phosphide dianion [{Sn(μ-PMes)}2(MesP)2]2− (Mes = 2,4,6-Me3C6H2)
Abstract
In contrast to the reactions of other primary phosphides with Sn(NMe2)2, the reaction of MesPHLi with Sn(NMe2)2 results in partial coupling of MesP groups in the product (which contains the novel Sn(II) dianion [{(Sn(μ-PMes)}2- (MesP)2]2−).
