✦ Synopsis


The carbon-13 chemical shifts of monosubstituted cyclohexane derivatives are compared with those of aliphatic compounds. The polar substituents exert a similar influence on the M-, Band y-carbons in both series of compounds. The 8-effect is shown to be characteristic mainly to the cyclic compounds, however. The appearance of a 8-effect is discussed as a possible consequence of electron delocalization in alicyclic molecules. A correlation of these &effects with inductive parameters of the substituents is presented.
