Selenation of 2-chloro- and 2,6-dichloro-1,5-naphthoquinones with benzeneselenolate ion, generated from diphenyl diselenide and tributylphosphine in an alkaline medium, afforded 2-phenylseleno- and 2,6-bis(phenylseleno)-1,5-naphthoquinones in excellent yields. Reaction of halo-1,4-naphthoquinones with 3-amino-2-pyridineselenolate ion generated from bis(3-amino-2-pyridyl) diselenide gave naphtho[2,1-b]pyrido[3,2-e][1,4]selenazines and pyrido[2,3-b]pyrido[3″,2″:5′,6′][1,4]selenazino[2′,3′:3,4]naphtho[1,2-e][1,4]selenazines in high yields.
2-氯-和2,6-二氯-1,5-萘醌与二苯基二硒化物和三丁基膦在碱性介质中生成的苯硒酸根离子进行硒化,得到2-苯基硒-和2,6-双(苯基硒)-1, 5-萘醌收率极佳。卤代 1,4-萘醌与双(3-氨基-2-吡啶基)二硒化物生成的 3-氨基-2-吡啶硒酸根离子反应,得到萘并[2,1-b]吡啶并[3,2-e][1 ,4]硒嗪和吡啶并[2,3-b]吡啶并[3″,2″:5′,6′][1,4]硒嗪基[2′,3′:3,4]萘并[1,2- e][1,4]硒嗪的产率很高。
