The effect of solvent upon the rates and mechanisms of organometallic reactions. : II. Molecular complexes of methyltin halides and tin tetrahalides

Abstract

Methyltin halides give solid molecular complexes with the organic solvents normally employed in organometallic chemistry. Me 3SnBr gives complexes of the type Me 3SnBr·L with monodentate ligands (Py, DMSO, DMF, HMPT) and complexes of the type 2Me 3SnBr·L with bidentate ligands (dioxane, TMED). Me 2SnHal 2, MeSnHal 3 and SnHal 4 give complexes containing either two monodentate ligands or one bidentate ligand.
