It is shown that cycloadditions of 1,3-bis(dimethylamino)pentalenes and their Eazaanalogues with activated alkines are frontier orbital controlled whereas protonation is charge controlled. Formal [2+2]-cycloadditionsof pentalenes with activated alkines provide an interesting method X +'N X X 03 I,',
