Synthesis of 1,1-bis-{2-Hydroxy-3-[1'-Phenyl/H-5'-Aryl-Pyrazolin-3'-yl]-5-Methyl Phenyl} Methanes

摘要

Some new 1,1-bis-{2-hydroxy-3-[1'-phenyl/H-5'-aryl-pyrazolin-3'-yl]-5-methyl phenyl} methanes (7a-h and 8a-h) have been synthesized by the action of 1,1-bis{2-hydroxy-3-(3-aryl-prop-2-en-1-one)-5-methyl phenyl} methanes (5a-h) with phenyl hydrazine hydrochloride and hydrazine hydrate in pyridine medium.
