A CONVENIENT SYNTHESIS OF 3,5'-BIPYRAZOLYL DERIVATIVES VIA HYDRAZONYL HALIDES
Hassaneen, Hamdi M.,Shawali, Ahmad S.,Elwan, Nehal M.
, p. 1041 - 1047 (2007/10/02)
Cycloaddition of N-phenyl-C-cinnamonitrilimine 3 with enolates of various active methylene compounds afforded the 3-styrylpyrazole derivatives 6-10 in high yields. 3-Styrylpyrazoles 6-13 reacted with diphenylnitrilimine 20 to give corresponding 3,5'-bipyr
