ABSTRACT The present invention provides a process for pre- paring an organic solvent solution of a lower trialkyltin hydride in high yield and purity, with a minimum of handling steps and occasions for persons to be exposed to hazardous materials. The process comprises reacting a lower trialkyltin chloride with an alkali metal bis(2-alkyoxyethoxy)aluminum dihydride in the presence of a hydrocarbon solvent boiling in the 50° to 200°C range, whereby a solution of the lower trial- kyltin hydride is obtained. The lower trialkyltin hydride produced by the process of the invention can be readily sep- arated by distillation from unchanged trialkyltin chloride starting material. The proportions of alkali metal bis(2- alkoxyethoxy)aluminum dihydride to trialkyltin chloride in the present process suitably range from 0.3 mole to 1 mole of the former per mole of the latter. The lower trialkyltin hydride so produced is conveniently utilized in solution as a reactant in an addition reaction ("hydrostannation") or as a reducing agent of controlled activity ("hydrostannolysis").
