Stability and spectral characteristics of 3-methyl-3-phenyl-1-arylphthalyl ions

Abstract3-Methyl-3-phenyl-1-aryphthalyl ions are more stable than 3,3-diphenyl ions, but less stable than 3,3-dimethyl-1-arylphthalyl ions. The effect of substituents at C(3) and C(1) on stability and spectral characteristics of the ions is discussed.

Reaction of thiophthalylium salts with primary aromatic amines

It is shown that the reaction of 1,3,3-triphenylthiophthalylium perchlorate with aniline and o- and p-toluidines proceeds with retention of the thiophthalane ring to give, depending on the reaction conditions, N- or C-substituted derivatives of amines.
