Observation of Zwitterions in the Thermal Reaction of Ketenes with Carbon-Nitrogen Double Bonds

View publication

Abstract

Zwitterions have been detected in thermal reactions of ketenes with imidazoles. The direct observation of the zwitterions firmly establishes that the thermal cycloaddition of ketenes with carbon-nitrogen double bonds is a two-step process. © 1982, American Chemical Society. All rights reserved.
