4-Vinyl-1,3-oxazoilidin-2-imine derivatives have been synthesized by cycloaddition reactions of 2-vinyloxiranes with unsymmetrical carbodiimides catalyzed by palladium(0) complexes in excellent total isolated yields. After reaction two compounds were alwa

The N-phenylquinolinium salt 4 reacts with ketene diethyl acetal (5) by angular anellation to give 6.On the contrary, with ynamine 2 an open-chain 1 : 2 adduct (14) with cross-conjugated cyanine structure is obtained which is proved by X-ray analysis.With
