摘要

The title reaction of substituted styrenes, l-phenyl-1, 3-butadiene, and some cyclic aryl- conjugated ethylenes proceeds smoothly at room temperature, affording the corresponding oximes in moderate to nearly quantitative yields. The reaction mechanism is discussed on the basis of the formation of an alkylcobalt intermediate and its subsequent reaction with ethyl nitrite.
