Abstract

Abstract The 13 C chemical shifts of 11 substituted triphenylamines have been determined and the assignment of these resonances made using intensities, 1 H and 19 F couplings and predictions from bond additivity relationships. 13 C chemical shifts at carbons bearing the substituent and at carbons ortho to the substituent correlated reasonably well with the Q parameter. A multiple regression analysis of chemical shifts with the field and resonance ...
