Synthesis and spectral studies of some novel 2,5,9,10-tetrahydro[7,8-g]benzo-8-arylpyrazolo[4,5-e][1,5-b]benzoxazon ine via phase transfer catalysis

Article abstract of DOI:10.1080/00397919708004094

Treatment of 1H-4,5-dihydro-3-aryl-5-(2-hydroxyaryl)pyrazole with o-dibromoxylene under liquid-liquid phase transfer catalytic conditions using tetra-n-butylammonium hydrogen sulphate or [18]-crown-6 as PT catalyst, benzene/chloroform as organic phase and 50% aqueous potassium hydroxide as second phase, afforded novel 2,5,9,10-tetrahydro[7,8-g]benzo-8-arylpyrazolo[4,5-e][1,5-b]benzoxazon ines.
