Data collection method:

DFT study: - DFT optimized 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, 4-methylbenzyl alcohol and 2 molecule of D-mannose based monomer 1 (1-O-methyl-2,3-O-isopropylidene-4,6-O-carbonate-α-ᴅ-mannopyranose) to account for the propagation step of ring-opening polymerization, via a primary alcohol chain intermediate. Protocols: rwB97XD/6-311++G(d,p)/6-31+G(d)cpcm=dichloromethane/T=298.15K Content: - Gaussian09 rev D.01 output files - ROP_propagation from a primary alcohol.pdf, illustrating the calculations made and summarizing the free enthalpies computed.
