New bis(chalcones) and their transformation into bis(pyrazoline) and bis(pyrazole) derivatives

The reaction of bis(chalcones) 1a-d and bis(chalcone) tetrabromo derivatives 3a-d with hydrazine hydrate gave bis(pyrazolines) 4a-d and bis(pyrazoles) 5a-d, respectively. Bis(pyrazoles) 5e,f bearing hydroxyphenyl substituents have been prepared from the r
