Abstract
2-(1-Aryl-2-methoxyethenyl)benzaldehydes 2, obtained by successive treatment of 1-(1-aryl-2-methoxyethenyl)-2-bromobenzenes 1 with BuLi and 1-formylpiperidine, were transformed to the corresponding phenylhydrazones 3 on treatment with PhNHNH2. When these hydrazones were allowed to react with conc. HBr, cyclization, followed by dehydrogenation with air occurred, furnished 3-aryl-2-methoxyinden-1-one (Z)-phenylhydrazones 4.
