What is Infrared and Nuclear Magnetic Resonance Properties of Benzoyl Derivatives of Five-membered Monoheterocycles and Determination of Aromaticity Indices about?

## Abstract Benzophenones, 2‐benzoylthiophenes, 2‐benzoylpyrroles, and 2‐benzoylfurans, which have substituents at __m__‐ and __p__‐positions of the benzoyl ring were prepared and their ir and nmr spectra were obtained in 0.1 __M__ chloroform‐__d__ solution. The chemical shift values of each series were plotted against the Hammett substituent parameters to give good correlation, with the exception of the __ortho__‐Hs and ‐Cs. The slopes as well as the differences in chemical shift gave sets of meaningful values for the indices of aromaticy.
