    • This imine was used as a model in our previous study of the reaction of dimethylsulfonium derivatives (see reference [28]). The rotamer with the sulfinyl oxygen atom in a (s)-cis arrangement with respect to the C=N bond was the most stable. However, solvent effects and stabilizing interactions within the transition states can dramatically modify the conformation around the N-S bond.
