Structure-Solubility Relationship of 1,4-Dioxane Complexes of Di(hydrocarbyl)magnesium.

ABSTRACT: Systematic variation of the 1,4-dioxane (dx) concentration during the precipitation of sparingly soluble [MgBr₂ (dx)₂ ] from ethereal Grignard solutions of RMgBr has allowed the structural investigation of crystallized [R₂ Mg(dx)_n ] (n=1, 1.5, 2, and 3), which form during this dioxane method, depending on the bulkiness of R. The numbering of the complexes explored in this study is based on the number n of dioxane molecules per magnesium atom, followed by the substituent R; an apostrophe denotes coordination polymers. The following derivatives were studied by X-ray crystal-structure determination and NMR spectroscopy: n=1: [Me₂ Mg(μ-dx)]_∞ (1'-Me) and [nPr₂ Mg(μ-dx)]_∞ (1'-nPr); n=1.5: [{iPr₂ Mg
