Reaction of oximes of-diketones with diphosphorous tetraiodide for preparation of oxadiazoles and nitriles

10.1080/00397911.2011.595035

The study primarily investigates the use of diphosphorus tetraiodide (P2I4) as a novel and mild condensing agent for the synthesis of oxadiazoles and nitriles from the oximes of α-diketones. The research explores the dehydration of oximes to form 1,2,5-oxadiazoles and the rearrangement of oximes to produce the normal Beckmann product, 1,2,4-oxadiazole. Key chemicals used in the study include dioximes derived from α-diketones, such as benzildioxime, and various substituted 1,2-dioximes, which serve as substrates for the synthesis of oxadiazoles. The study also examines the effects of different solvents on the reaction, with chlorinated solvents, particularly dichloromethane, proving to be the most effective. The purpose of these chemicals is to facilitate the synthesis of oxadiazoles, which are an important class of heterocycles used in a variety of bioactive molecules, and nitriles, through a simple and efficient method.
