Abstract
Abstract Amino and amido carboxylates of divalent tin, zinc, cobalt and nickel which are useful as catalysts for polyurethane formulations. Such compounds correspond to either of the formulae: ##STR1## wherein R 1 and R 2 are independently C 1 -C 20 alkyl, C 6 -C 20 cyclohydrocarbyl, C 2 -C 20 hydroxyalkyl or alkoxyalkyl, or R 1 and R 2 together with N form a nitrogen-containing heterocyclic ring of 5 or 6 atoms; R 3 is a --CH 2 ) n group where n is an integer from 2 to 6 or a ##STR2## group where R 4 is an alkyl, cycloalkyl or aryl group of up to 6 carbon atoms; A is ##STR3## wherein R 5 and R 6 are independently hydrogen, C 1 -C 4 alkyl or R 5 and R 6 together form part of a six-member cyclohydrocarbyl ring, and M is divalent tin, zinc, cobalt or nickel.
