Abstract
Optionally chelated tetracoordinated or pentacoordinated tin(IV) compounds having the general formula: ##STR1## are useful latent catalysts in compositions for the preparation of polyurethanes, or for the crosslinking of organopolysiloxanes, by increasing the temperature of appropriate reaction mixtures to a level above the decomposition temperature of such tin(IV) compound.
