Anionic synthesis of well-defined polymers with amine end groups

The results for efficient tertiary and primary amine functionalization of p olymeric organolithium compounds in hydrocarbon solution at room temperatur e are described for termination reactions with N-trimethylsilylbenzophenone imine, 3-dimethylaminopropyl chloride and 2,2,5,5-tetramethyl-1-(3-chlorop ropyl)-1-aza-2,5-disilacyclopentane. Functionalizations with the functional ized initiator, 2,2,5,5-tetramethyl-1-(3-lithiopropyl)-1-aza-2,5-disilacycl opentane are presented. Conditions for quantitative amine functionalization were observed for all of these reactions and reagents.
