| Abstract: | The singlet oxygen photolysis of methyl 2-benzimidazolecarbamate (Carbendazim, 1) in aqueous hydrochloric acid has been investigated. 2-Guanidinobenzimidazole 7, benzimidazole 9, 2,4′- (13) and 2,5′-bibenzimidazole 14, were isolated from the reaction products and identified. A comparative study on the singlet oxygen photolysis of Benlate 2 both in MeOH and aqueous hydrochloric acid, was also undertaken. |
