IR & NMR Spectral Studies of some 7-Substituted 9H-Fluorenacyl Bromides: Assessment of Substituent Effects

Full Text PDF

Abstract:

A series of some 2-bromo-1-(2-substituted 9H-fluorene-7-yl)ethanones have been prepared. The purities of these ethanones have been checked by their physical constants and spectroscopic data. The spectral group frequencies of these enones have been assigned and correlated with Hammett substituent constants, F and R parameters. From the results of statistical analyses, the effects of substituent have been discussed.
