In reaction with diphenylcyclopropenone dimethylselenonioindanedionide only forms 5-oxo-3,4-diphenylindeno-2-pyrone.The reaction of diphenylcyclopropenone with dimethylselenoniodimedolide leads to the formation of condensed α- and γ-pyrones and also the product from addition of the ketocarbene of dimedone at the double bond of cyclopropenone and dimedone α-phenylcinnamate.The sulfonionindanedionide forms the 2-indenopyrone appreciably more slowly than the selenonium analog and with half the yield.Condensed pyrones are not formed at all in the reaction of the sulfoniodimedonide.
