Abstract
Abstract Amino and amido dialkyltin dicarboxylates and stannoxy carboxylates are prepared by first reacting an amine or amino alcohol with a dicarboxylic acid anhydride, followed by reaction of the resulting product with a dialkyltin oxide. The obtained compounds are useful as catalysts for promoting reaction of organic isocyanates with organic compounds having one or more active hydrogen-containing groups.
