Abstract
We report on the reactivity of magnesium(I) dimers, [Mg(nacnac)]2 (nacnac = HC[C(Me)N(2,6-iPr2C6H3)]2 ([DippLMg]2) and HC[C(Me)N(2,4,6-Me3C6H2)]2 ([MesLMg]2)), towards the phosphaalkyne tBuCP. The steric profile of the magnesium(I) dimer results in selectivity for different products. The larger diisopropylphenyl derivative yields exclusively the monomeric dimagnesiated phosphaalkene [DippLMg]PC(tBu)([DippLMg]) (1), while the mesityl derivative facilitates reductive coupling of two phosphaalkyne equivalents to give access to the 1,3-diphosphacyclobutadienediide [MesLMg]2[(tBu)2C2P2](2). The reactivity differs in coordinating solvents such as THF, which allowed for the observation of C-P coupled products. For sake of comparison, reactions of magnesium(I) compounds with Me3SiCN were carried out. In contrast to the reactions involving tBuCP, these afforded 1,3-diazabutadienediyl complexes via reductive coupling and silyl migration processes.

Abstract
The molecular structure of 2,4-di-tert-butyl-eta4-1,3-diphosphacyclobutadiene tin has been determined in the gas phase by electron diffraction using both the DYNAMITE and SARACEN methods. The suitability of many different theoretical methods for the calculation of structures of half-sandwich main-group metal complexes has been investigated, and, by comparison of the results with the experimental structures, suggestions have been made as to the most suitable methods for this class of compound.
