Decomposition of 2-Azido Ketones to 2-(Acetylamino)-2-alken-1-ones by Perrhenate Catalysis
The thermally induced elimination of nitrogen from cyclic and acyclic 2-azido ketones 2 is accelerated by catalytic amounts of perrhenate.In acetic anhydride - if necessary in the presence of small amounts of a mineral acid - 2-(acetylamino)-2-alken-1-ones 3 are formed in good yields.The decomposition rates of the catalysed and the uncatalysed thermolysis are compared.
