A simple cobalt-based catalyst system for the controlled dehydropolymerisation of H3B•NMeH2 on the gram-scale

A simple Co(ii)-based amine-borane dehydropolymerisation catalyst system is reported that operates at low loadings, to selectively give (H2BNMeH)(n) polymer on scale, with catalyst control over M-n, narrow dispersities and low residual metal content.
