The reactions of iodine monochloride and iodine monobromide with a tetraalkyltin (butyl) and a tetraaryltin (phenyl) have been studied with a view to establishing their utility as routes to organotin chlorides and bromides respectively. Rapid high yield syntheses of the triorganotin bromides, diorganotin dichlorides and trialkyltin chloride were achieved. Some further suggestions are made on the mechanism

chemical shift of equimolar mixtures of acid and base as a function of concentration in chloroform. Additional studies used the analogous Lewis monodentate base methyldiphenylphosphineoxide (MPPO) and the Lewis base triphenylphosphine oxide (TPPO). In all cases, formation of a adduct was found to predominate. Comparison of the equilibrium constants for specific organotin halides showed that EDPO and

completely dissociated in acetone solution, the diorganotin(IV) derivatives dissociate only partly and the tri- and tetrahalidetin(IV) complexes probably retain the hexacoordinate configuration. The crystalstructure of [(L′)2(Me)3Sn]Cl (1) has been determined by X-ray analysis. The tin atom is coordinated to three methyl groups and two 4-phenylimidazole donors in a substantially regular trigonal bipyramidal

Tri-n-butyltin bromide or iodide and di-n-butyltin dibromide or diiodide may be conveniently prepared from the corresponding organotinchlorides by tetra-n-butylammonium halide-catalyzed halogen redistribution reactions with suitable alkyl bromides or iodides. However, similar transformations are not feasible for trimethylhalosilanes.
