Abstract

Pyrolysis of calcium salt of alkoxybenzoic acid leads to the formation of alkoxybenzoic ester instead of alkoxy benzophenone.

GRAPHICAL ABSTRACT

ACKNOWLEDGMENT

We are grateful to the Council of Scientific and Industrial Research (CSIR) for providing a SRF-NET fellowship to K. S.

Notes

a Yield was calculated based on 2 equivalents of calcium salt producing 1 equivalent of esters. All the compounds are known compounds and the spectroscopic data [infrared (IR), 1H NMR, and 13C NMR] of the synthesized compounds are in good agreement with the literature reports.[ Citation 4 Citation 5 Citation 6 Citation 7 Citation 8 Citation 9 Citation 10 Citation 11 Citation 12 Citation 13 Citation 14 Citation 15 Citation 16 ] Thin-layer chromatography (TLC) of the synthesized compounds was also identical with the authenticated samples. To the best of our knowledge, such surprising observations have not been reported in the literature prior to this study.
