(Chemical Equation Presented) Different types of phosphonium carbanions were applied to 2-diazonio-1,3-dioxo-2,3-dihydro-1H-inden-2-ide (1) in order to synthesize a number of condensed and fused N-heterocycles. When 1 was treated with cyanomethyltriphenylphosphonium chloride oxadiazine-, and pyridazine derivatives were obtained whereas bis-indanylidene derivatives resulted from the reaction of 1 with methyl- and ethyltriphenylphosphonium bromides. On the other hand, a series of substituted and unsubstituted spiro[3′]pyrazoles were obtained from the diazo substrate when reacted with vinyl- and allyltriphenylphosphonium bromides.
