A new and efficient method of preparation of R2SnH2 is proposed.Organodioxastannolanes were used as starting materials, these compounds being easily obtained by azeotropic distillation of water from a solution of diorganotin oxides and 1,2 diols in cyclohexane.Their reduction by commercial BH3/THF complex gave raw dialkyltin dihydrides with excellent yields and high purity degrees.
