- 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.
