3-Substituted 1,4-Benzoquinone 4-oximes

Abstract

The preparation and physical properties of seven compounds in the title series are described. When the 3-substituent is F, Cl, Br, I, Me, or OMe the compounds exist predominantly (>95%) in the oxime form. The 3-methoxy-carbonyl derivative is estimated to exist in the nitroso form to the extent of 23%.
