N-Sulfonylbenzotriazoles. Part 2. Reactions of 1,1’-Sulfonyldibenzotriazole and 1-Benzenesulfonyl-1,2,4-triazole with Alcohols; a New Approach to N-Alkylbenzotriazoles and N-Alkyl-1,2,4-triazoles

1,1’-Sulfonyldibenzotriazole (3) reacts with sodium alkoxides to give N-alkylbenzotriazoles. With alkanols, benzotriazolium alkyl sulfates are produced. 1-Benzenesulfonyl-1,2,4-triazole with the sodium salts of alcohols gives 1-alkyl-1,2,4-triazoles. The mechanisms of these reactions are discussed.
