Zusammenfassung:The present invention relates to hexacoordinated tin(IV) compounds of the general formula: The compounds of formula (1) are prepared by a hydrostannation reaction of a diorganotin dihydride on an enol alcoholate or carboxylate. The compounds of formula (1) are latent catalysts which can be used especially for the preparation of polyurethanes and the crosslinking of silicones because they decompose thermally into diorganotin dicarboxylates or dialcoholates.
