Abstract

The syntheses of three stable, isolatable tripyridiniumylpropenyl anions are described. 1, 2, 3-Tris (4-(N-methylpyridiniumy1)) propenyl anion and 1-(benzenesulfonyl)-1, 2, 3-tris (4 (N- methylpyridiniumyl)) propenyl anion were prepared by treating the corresponding cyclopropane with a base. 1, 3-Bis (benzenesulfonyl)-1, 2, 3-tris (4-(N-methylpyridiniumy1)) propenyl anion was prepared by nucleophilic attack of benzenesulfinate anion on~-( ...
