Photoinduced Ring Opening of Methyl 1-Aryl-5-oxo-6,7-dihydro-1H,5H-pyrazolo[1,2-a]pyrazole-2-carboxylates in the Presence of Diaryl Disulfides

چکیده
Among the methods used for synthesis of functionalized heterocyclic compounds, photochemistry has gained immense popularity due to reactivity intermediates in photoinduced reactions. In this study, we report on effect diaryl disulfides as hydrogen atom transfer catalysts transformations pyrazolo[1,2-a]pyrazolones. After excitation with visible light, these compounds are susceptible C–N bond cleavage, followed by intermolecular abstraction. By modifying reaction conditions, have developed two novel highly substituted pyrazoles.

In the title mol-ecule, C(12)H(13)N(5)O(2)S, a bifurcated intra-molecular N-H⋯O(O) hydrogen bond forms two S(6) ring motifs. The benzene ring forms a dihedral angle of 14.36 (11)° with the pyrazole ring. In the crystal, pairs of N-H⋯S hydrogen bonds form centrosymmetric dimers, generating R(2) (2)(8) ring motifs, which stack along the b axis.
