摘要

Abstract: More than 60 new substituted fluoronaphthalenes, and two new substituted fluorobiphenyls, have been synthesized and their I9F chemical shifts measured. An analysis of the data provided the following conclusions.(1) Geometrical factors, as well as electronic interactions, appear to play a significant role in determining 19F chemical shifts of peri- substituted fluoronaphthalenes.(2) The electronic effect of the trifluoromethyl substituent is ...
