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.

Novel tetracoordinated tin (IV) compounds, well suited as latent catalysts for the preparation of polyurethanes or for the crosslinking of curable diorganopolysiloxanes (upon thermal decomposition thereof into diorganotin dicarboxylates or dialcoholates), have the general formula (1): STR1 in which the radicals R, which may be the same or different, are each a linear or branched chain C1 -C20 alkyl radical, a mononuclear aryl radical, or an aralkyl or alkaryl radical, the alkyl moieties of which having from 1 to 6 carbon atoms; the radicals R1 and R2, which may be the same or different, are each a hydrogen atom, a cyano radical, a C1 -C6 alkyl radical, or an alkoxycarbonyl radical, the alkyl moiety of which having from 1 to 6 carbon atoms, with the proviso that R1 and R2 may together form a saturated hydrocarbon ring member having from 5 to 8 carbon atoms; the radical R3 is a hydrogen atom, a linear or branched chain C1 -C20 alkyl radical, a linear or branched chain C1 -C20 alkoxy radical, a mononuclear aryl radical or a mononuclear aryloxy radical; and a is 0 or 1.
