Synthesis published new progress about Rearrangement. 27412-71-1 belongs to class pyrazoles-derivatives, name is 5-Phenyl-1H-pyrazol-3(2H)-one, and the molecular formula is C9H8N2O, Safety of 5-Phenyl-1H-pyrazol-3(2H)-one.

Omar, Mohamed T. published the artcileA new synthetic route to 3-oxo-5-phenyl-2,3-dihydropyrazoles, Safety of 5-Phenyl-1H-pyrazol-3(2H)-one, the main research area is pyrazolone phenyl; phenylpyrazolone; hydrazine benzylidenethiazolidinedione rearrangement.

The reaction of RNHNH2 (R = H, Me) with benzylidenethiazolidinediones I (R1 = PhCH2, Et, allyl) gave the resp. pyrazolones II. I (R1 = PhCH2) was heated with PhNHNH2 in EtOH to give II (R = Ph) and addition product III; a mixture of III, pyridine, Et3N, and EtOH was refluxed 4 h to give II (R = Ph).
