reactivity of the selenenamide bond in selenazoles toward nucleophiles can be exploited for synthesis of other organoselenium compounds. It has been found that benzisoselenazol-3(2H)-ones and related selenaheterocycles with an Se-N moiety treated with Grignard reagent gave unsymmetrical aryl-aryl and aryl-alkyl selenides in moderate to good yields. This reaction has a synthetic value because it is highly
