1.The vinyl esters exist predominantly in the S-trans conformation with a syn orientation: of the vinyl and carbonyl group, which is stabilized by a weak C-H...O intramolecular hydrogen bond with the participation of the a proton of the vinyl group.2.In the vinyl ester of picolinic acid the carbonyl group exists predominantly in the S-trans-(N) conformation; in the vinyl ester of nicotinic acid the carbonyl group exists in both the S-cis-(N) and S-trans conformations; in the vinyl ester of furan-2-carboxylic acid the carbonyl group has a predominantly S-cis(O) conformation. |
