Synthesis of 2H-Azirines by Iridium-Catalyzed Decarboxylative Ring Contraction of Isoxazol-5(4H)-ones

A phosphine-free iridium-catalyzed reaction of isoxazol-5(4H)-ones (isoxazolones) has been developed, and affords 2H-azirines through decarboxylation and ring contraction. This method provides an efficient and environmentally benign protocol which could replace the conventional approaches used to synthesize 2H-azirines.

Steady-State and Laser Photolysis Studies of Substituted 2H-Azirines. Spectroscopy, Absolute Rates, and Arrhenius Behavior for the Reaction of Nitrile Ylides with Electron Deficient Olefins

The photobehavior of 2,2-diphenyl-3-methyl-2H-azirine (15) and 2-methyl-2,3-diphenyl-2H-azirine (14) was investigated in solution at 298 K.Both azirines undergo ready ring opening on exposure to UV light to give nitrile ylides which can be trapped with me
