Synthesis of 6-membered cyclic carbonates from 1,3-diols and low CO2 pressure : a novel mild strategy to replace phosgene reagents
Georgina Gregory, Marion Ulmann and Antoine Buchard*
DFT study: Optimised structures of local minima and transition states from the potential energy surface of the tosylation and cyclisation steps in the synthesis of cyclic carbonate (R)-4-Methyl-[1,3]-dioxan-2-one from CO2 and (R)-1,3-butanediol.
Protocol: rωb97xD/6-31+g(d)/ SCRF=(cpcm,solvent= chloroform)
