N-[(5-Azido-1,3-diphenyl-1H-pyrazole-4-yl)methylene]-N-arylamines (4a-c) and N-[(5-Substituted-1,3-diphenyl-1H-pyrazole-4-yl)methylene]hydrazides (5a-e) were prepared from 5-azido-1,3-diphenyl-1H-pyrazole-4-carbaldehyde (3) and 5-chloro-1,3-diphenyl-1H-pyrazole-4-carbaldehyde (2), respectively. Thermolysis of (4a-c) and (5d-e) afforded 5-arylamino-...
