Abstract

The effect of a heterosubstituent on the result of the reduction of 3-nitro-4-substituted coumarins with sodium hydrosulfite, which generally leads to a mixture of three compounds, viz., the product of the reduction of the nitro group to an amino group and products of its replacement by hydrogen or a mercapto group, was studied. The result of the transformation is explained by the stabilizing effect of the heterosubstituent on the reaction intermediate.
