ilyl)phenyl]iodonium triflates were prepared for the generation of benzynes bearing ketone function. Treatment of the iodonium triflates with Bu4NF in CH2Cl2 in the presence of furan at room temperature gave 6-acyl-1,4-epoxy-1,4-dihydronaphthalenes in high yields. The mild conditions and the tolerance of the ketone function on benzyne generation are attributable to the advantage of hypervalent iodine
制备[5-酰基-2-(三甲基甲硅烷基)苯基]碘鎓三氟甲磺酸酯以产生具有酮功能的苯并炔。在室温下,在呋喃存在下,在CH 2 Cl 2中用Bu 4 NF处理三氟甲烷碘鎓,以高收率得到了6-酰基-1,4-环氧-1,4-二氢萘。温和条件和酮功能对苯炔生成的耐受性归因于高价碘化合物的优势。
