Abstract

We present a convenient method to synthesize polymers with primary amino groups by end-capping of living anionic chain ends with nitrites followed by reduction in a one-pot process. As an example, the addition of pivalonitrile to the chain ends of oligobutadienyllithium in toluene, followed by the reduction with sodium borohydride quantitatively leads to omega-amino-oligo-1,4-butadiene, as demonstrated by H-1 and C-13 NMR, thin-layer chromatography and MALDI-ToF mass spectrometry.
