✦ Synopsis

New pyrazo10- [3,4-b]-[!, 51-benzoazepinone derivatives are reported. One pot reactions of 5-chbro-4-carboxy-1 -phenyl (3-substituted) pyrazole derivatives with o-thioarninophenol, o-phenybnediarnine, and oarninophenol derivatives were realized. The influences of the polarizability of the heteroatorns on the reaction rates and chemical yields are discussed.
