The unusual anodic reactivity of tertiary enamines in the presence of base: the effect of the nature of the base on the product distribution
Abstract
The anodic oxidation of aromatic N-methyl-N-phenylenamines leads to dimers and trimers in the presence of K2CO3, whereas in the presence of 2,6-lutidine demethylation occurs and, in one case, this is subsequent to cyclisation and results in a new 3H-indole.
