A mild and reproducible method for the formation of a nonstabilized azomethine ylide was developed by photoinduced reaction catalyzed with eosin Y under green light irradiation. Resulting 1,3-dipole was trapped with fluoroalkenes, fluoroalkylated alkenes,

The 1,3-dipolar cycloaddition of an intermediary iminium ylide formed from N-benzyl-N-(methoxymethyl)trimethylsilylmethylamine to conjugated olefinic and acetylenic dipolarophiles in the presence of a catalytic amount of trifluoroacetic acid has been found to give 3- or 3,4-substituted pyrrolidines and 2,5-dihydropyrroles.
