Cyclopolymerization. IX. Effect of β -Substituents on the Cyclopolymerization of Diallylamines

Abstract

ESR studies and analysis of the products from the cyclopolymerization of substituted diallylamines show that the cyclization may not involve a concerted process, and that the proportion of piperidine rings formed is increased by the use of bulky or conjugated/3-substituents, or increased reaction temperatures, factors which favor thermodynamic control of the direction of ring closure. Increased piperidine ring content causes a small reduction in the basicity of the polymers. © 1976, Taylor & Francis Group, LLC. All rights reserved.
