Anionic synthesis of well-defined polymers with amine end groups

Abstract

The results for efficient tertiary and primary amine functionalization of polymeric organolithium compounds in hydrocarbon solution at room temperature are described for termination reactions with N-trimethylsilylbenzophenone imine, 3-dimethylaminopropyl chloride and 2,2,5,5-tetramethyl-1-(3-chloropropyl)-1-aza-2,5-disilacyclopentane. Functionalizations with the functionalized initiator, 2,2,5,5-tetramethyl-1-(3-lithiopropyl)-1-aza-2,5-disilacyclopentane are presented. Conditions for quantitative amine functionalization were observed for all of these reactions and reagents.
