Abstract
A synthetic utility of [bis (trifluoroacetoxy) iodo] benzene on α, β-unsaturated carboxylic acid is described. This is the first example of preparation of vinyl azide using α, β-unsaturated carboxylic acids directly by using hypervalent iodine reagent. The advantage of this protocol is characterized with non-toxicity of starting material and shorter reaction times to obtain good preparative yields. The method is also useful for the preparation of acyl azides.
