1,3-DIPOLAR CYCLOADDITION REACTIONS OF SOME 3-ARYL-PHTHALAZINIUM-1-OLATES
Celebi, N.,Tuerker, L.
, p. 625 - 630 (2007/10/02)
The participation of halogen substituted 3-aryl-phthalazinium-1-olates in cycloaddition reactions were studied with various olefinic and acetylenic dipolarophiles.The betaines gave the expected cycloadducts with vinyl acetate, vinyl phenyl ether, and viny
