An Efficient Synthesis of Highly Substituted Spiro [Fluorene-9,3′-[1,2,4]Triazoles from the Reaction of N 3 -Substituted Amidrazones with (2,4,7-Trinitro-9 H -Fluoren-9-Ylidene)Propanedinitrile
Novel spiro[fluorene-9,3′-[1,2,4]triazoles were obtained in excellent yields from the reaction of N3-substituted benzamidrazones and (2,4,7-trinitro-9H-fluoren- 9-ylidene)propanedinitrile in ethyl acetate solution at ambient temperature. The react ion mechanism is discussed.
