Full size image The asymmetric center is created during the first hydrogenation step and is conserved throughout the catalytic cycle. The second hydrogenation proceeds throughTS2(S),which is lower in free energy compared withTS(S). Therefore, the level of enantioselection is determined by the rela...

Full spectrum is available in Supporting Information). The data of DS obtained from NMR spectra are presented in Table 1. Although the cellulose solution viscosity decreases with increasing DMSO content in a binary solvent, the DSs of samples are not much changed until the ratio 1:1 IL:DMSO...
