Abstract
The cycloaddition of aromatic nitroso compounds pX-CsH4NO with diphenylketene occurs in all cases rapidly and with relatively low regioselectivity, which is little affected by solvents or substituents. With X= CH30. CH3, H, and CHaOzC, the principal product is the 2-aryl-4, 4- diphenyl-l, Z-oxazetidin-3-one. The isomeric oxazetidin-4-one, the main primary product for X=(CH3) 2S, is unstable in all cases and decomposes to car-bon dioxide and a Schiff ...
