摘要

The effect of X substituents on the C (a) chemical shift of the CN, COMe, and COOMe groups in 2, 6-di-methyl-4-substituted-benzonitriles DM-1, 2, 6-dimethyl-4-substituted- acetophenones DM-2, and methyl 2, 6-dimethyl-4-substituted-benzoates DM-3 has been studied. The data as such and after a dual substituent parameter (DSP) treatment have been compared with those obtained from the corresponding 2, 6-unsubstituted compounds 1, 2, ...
