DFT study of the reaction between TBD, benzylalcohol initiator, and one molecule of alpha/beta-methoxy-2-deoxy-D-ribose cyclic carbonate, or of trimethylene carbonate (ring-opening polymerisation initiation step)

Gregory,a Gabriele Kociok-Köhna and Antoine Bucharda,* a Department of Chemistry, University of Bath, Bath BA2 7AY - DFT optimised geometries and computed free enthalpies of local minima (intermediates) and local maxima (transition states) were used to investigate the mechanism of the reaction between TBD, benzyl alcohol and 1 molecule of alpha or beta-methoxy-2-deoxy-D-ribose cyclic carbonate cyclic carbonate to account for the initiation step of ring-opening polymerisation.
