Multivariate Regression with Substituent Shift Increments. IV. 2-(4-X-Phenyl)-1H-isoindole-1,3(2H)-diones and 3-(4-X-Phenyl)2H-1,3-benzoxazine-2,4(3H)-diones.
Original language description
Two series of para disubstituted benzenes were studied: 2-(4-X-phenyl)-1,3-dihydro-2H-isoindole-1,3-diones and 3-(4-X-phenyl)-3,4-dihydro-2H-1,3-benzoxazine-2,4-diones. Their H-1 and C-13 chemical shifts were correlated with substituent shift increments(SSI) aj and zj, respectively. Significant deviations from plain additivity were observed in the case of delta H3 and delta C13 chemical shifts. This can be explained by changes in diamagnetic anisotropy contribution induced by different twist of 4-substituent from the bezene plane caused by variable substituent in position 1.
