Benzazole derivatives: V. The reactivity of some 2-p-tolyl-and 2-p-methylstyryl-benzimidazolium salts
The reactivity of the p-substituted methyl group in 1-methyl-2-p-tolylbenzimidazolium and 1-methyl-2-p-methylstyrylbenzimidazolium iodides with p-nitroso-dimethylaniline (p-NDMA) and aromatic aldehydes was studied. According to literature data on the steric effects produced by the bulky N-l methyl g...

| description | The reactivity of the p-substituted methyl group in 1-methyl-2-p-tolylbenzimidazolium and 1-methyl-2-p-methylstyrylbenzimidazolium iodides with p-nitroso-dimethylaniline (p-NDMA) and aromatic aldehydes was studied. According to literature data on the steric effects produced by the bulky N-l methyl group, the 2-p-tolyl substituted salt does not react with p-NDMA. On the other hand, 2-p-methylstyryl substituted salts give condensation reactions, similarly to 1,2,3-trimethylbenzimidazolium iodides. The compounds obtained from the reaction with aromatic aldehydes can be used as dyeing substances, photosensitizers or as dienic monomers, due to the conjugated chain from C-2. |
