FeCl3 catalyzed one-pot solvent-free synthesis of 1-phenyl-1, 2-dihydro-3H-naphtho [1, 2-e] [1, 3] oxazin-3-one

Over the past few decades, chemistry has become a major science scholar for chemists. On the other hand, chemical reactions have long been caused the environmental problems. To overcome these problems and facilitate chemical reactions, alternative energy sources such as UV or microwave are used. Iron is one of the most abundant metals on Earth and FeCl3 (Iron (III) chloride) is an efficient catalyst in modern organic synthesis, environmentally friendly and atom-economical organic transformations that can increase the yield and speed of the reaction. In this study, for the first time, a FeCl3 catalyst, instead of a ferrites catalyst, will be used to synthesize 1-phenyl-1, 2-dihydro-3H-naphtho [1, 2-e] [1, 3] oxazin-3-one in the microwave. According to the results of synthesis and analysis of the composition of the catalyst can be used for other multicomponent reactions.
