An improved synthesis of isonitrosoacetanilides

Rewcastle, Gordon W.,Sutherland, Hamish S.,Weir, Claudette A.,Blackburn, Adrian G.,Denny, William A.

, p. 8719 - 8721 (2007/10/03)

A novel two-step synthesis of isonitrosoacetanilides [2-(hydroxyimino)-N- phenylacetamides] has been developed, involving the initial acylation of aniline derivatives with 2,2-diacetoxyacetyl chloride, followed by reaction with hydroxylamine hydrochloride. The method works equally well with a variety of different aniline derivatives, including those with poor aqueous solubility and those containing electron rich ortho-substituents, neither of which react well under traditional conditions.
