1-Methyl-2-phenyl-4-arylphthalazinium perchorates, which exhibit the characteristics of CH acids, were obtained by the action of methylmagnesium iodide on 1-oxo-2-phenyl-4-aryl-1,2-dihydrophthalazines (Ar = C/sub 6/H/sub 5/, p-CH/sub 3/C/sub 6/H/sub 4/, p-C/sub 2/H/sub 5/OC/sub 6/H/sub 4/, p-FC/sub 6/H/sub 4/, p-ClC/sub 6/H/sub 4/, p-BrC/sub 6/H/sub 4/) followed by decomposition of the reaction mass with 57% perchloric acid. The 1-methylphthalazinium salts condense with benzaldehyde, giving 1-styryl-2-phenyl-4-arylphthalazinium perchlorates.
