title: Fresh evidence for proposed zwitterionic intermediates.
abstract: A new selective and sensitive method for the detection of aliphatic amines has been developed with chloride-form anion-exchange resins and 2,4-dinitrotoluene. The reaction with tertiary amines can only be explained in terms of hitherto postulated zwitterionic intermediates.
