Abstract
N-substituted derivatives of 5-aza-2,8-dioxa-1-stannocyclooctane, which is a heterocyclic compound of tin(II), have been synthesized in high yields by transesterification of dimethoxy- or di-n-butoxytin(II) with di-ethanolamines. All the compounds are monomers in the vapor phase and the soluble species are associated to some degree in chloroform solution.
