Reaction of α-metalated isocyanides 1a-c, f with alkylideneamine oxides (nitrones) 4 affords the 2-imidazolidinones 8.The 6-metalated 2,3-dihydro-4H-1,2,5-oxadiazine of type 5 is postulated as decisive intermediate. - Benzonitrile oxide (17) reacts analogously with 1a and 1b to give 4-imidazolin-2-ones 18 and with 1e to give the 3-imidazolin-2-one 19. - Phenyl azide (20) reacts with two moles of 1b to give 5-(benzylidenamino)-4H,5H-1,2,3-triazoline 24.The reaction course is discussed.
