Synthesis of new multi-functionalised 1,1 '-carbonylbispyrazole derivatives

摘要

A new series of multi-functionalised 1,1'-carbonylbispyrazole derivatives were synthesised through cyclisation of pyrazole carbohydrazides with some substituted methylene malononitriles in very good yields. The structures of all synthesised compounds were established on the basis of NMR, IR, MS and elemental analysis.
