Abstract

Abstract The condensation products of 5‐amino‐1,3‐disubstituted‐pyrazoles with aromatic aldehydes were identified as 2,4‐dihydro‐2,5‐diphenyl‐4‐(phenylmethylene)‐3 H ‐pyrazol‐5‐imine derivatives Treatment of these products with mercaptoacetic acid gave new fluorine containing 1 H ‐pyrazolo[3,4‐ e ][1,4]thiazepin‐7‐ones.
