A synthesis in good to excellent yields of 23 4H-benzo[d][1,3]oxazin-4- ones, 18 of which are novel, from monosubstituted anthranilic acids and variously substituted phenyl isoselenocyanates without using any harsh reagents has been developed. The Se powder precipitated during the reaction could be efficiently recycled for the preparation of the aryl isoselenocyanates.
