Spirally twisted imidazolium iminyl ylide structures from 1,2-rearrangements in reactions of imidazolium dicyanomethanide 1,3-dipoles with maleic anhydride: new perspectives on the Boekelheide-Fedoruk ring expansions

The reactions of 1-substituted-imidazolium-3-dicyanomethanides with maleic anhydride gave new ylide products from a Michael reaction and 1,2-rearrangements. These experiments, combined with theoretical calculations, provide an interesting new perspective

1,3-Dipolar Cycloaddition of Azolium Dicyanomethylides

1,3-Dipolar cycloaddition of azolium N-dicyanomethylides, which have an azomethine ylide structure, to acetylenic dipolarophiles affords azolopyridine derivatives.The initial cycloadduct has been isolated for the first time.Using unsymmetrical dipolarophi
