## Abstract A detailed experimental and theoretical UV-spectral analysis of the tautomeric forms of 3-methyl-1-phenyl pyrazol-5-one and 1,3-diphenyl pyrazol-5-one as well as of the UV-irradiated photoinduced products of the latter compound were carried out. The experimental UV-spectra were compared

## Abstract magnified image A “one‐pot” method for the synthesis of __N__‐(1,3‐diphenyl‐1__H__‐pyrazol‐5‐yl)amides was developed by cyclization of benzoylacetonitrile (**1**) and phenylhydrazine in neat condition followed by acylation. The corresponding __N__‐(1,3‐diphenyl‐1__H__‐pyrazol‐5‐yl)amide
