Abstract

4-(diazoalkyl)-1-alkylpyridinium and 4-(diazoalkyl)-1-alkylquinolinium salts are made from corresponding pyridinyl and quinolinyl diazoalkanes via direct N-alkylation with appropriate alkylating reagent. These novel diazoalkanes show enhanced thermal and chemical stabilities than their precursors. They can undergo [3 + 2] cycloaddition reaction and transition metal catalyzed carbenoid transformations.
