| Abstract: | ![]()
Zinc chloride is an efficient and safe catalyst in the[3 + 2]cycloaddition reaction of organic nitriles with sodium azide in solventless condition.The corresponding S-substituted 1H tetrazoles were obtained under mild conditions.This method can overcome disadvantages such as:the use of toxic metals and expensive reagents,drastic reaction conditions,water sensitivity and the presence of dangerous hydrazoic acid. |
