In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 3889-13-2, name is 5-Nitro-2,3-dihydro-1,3-benzoxazol-2-one, introducing its new discovery. Recommanded Product: 3889-13-2
Synthesis of benz[d]oxazolones involving concomitant acetyl migration from oxygen to nitrogen
Heating of o-acetoxybenzoyl azides 6-10 in toluene leads to the Curtius reaction, which, when followed by closure of oxazolone ring with concomitant migration of acetyl group from oxygen to nitrogen, produces 3-acetoxybenz[d] oxazol-2(3H)-ones 11-15, which undergo hydrolysis with hot dilute hydrochloric acid to furnish benz[d]oxazol-2(3H)-ones 17-21. Thermal reaction of 2-hydroxy-5-nitrobenzoyl azide (22) in toluene finally yields a mixture of 5-nitrobenz[d]oxazol-2(3H)-one (20) and 5-nitrobenz[d]isoxazol-3(2H)-one (23).
