allowed the synthesis of 2-arylselanylfurans, -thiophenes, and -selenophenes in moderate to excellent yields. An efficient protocol to access 2-arylselanylbenzo[b]chalcogenophene derivatives through the Cu(I)-catalyzed annulation of vinyl selenides is described. The key vinyl selenides were easily prepared from properly functionalized 1,1-dibromostyrenes and the method allowed the synthesis of 2-arylselanylfurans
摘要 描述了一种通过Cu(I)催化的乙烯基硒化物的环化反应获得2-芳基硒基苯并[ b ]硫属元素衍生物的有效方案。关键的乙烯基硒化物可以容易地由适当官能化的1,1-二溴苯乙烯制备,并且该方法允许以中等至优异的产率合成2-芳基硒基呋喃,-噻吩和-硒代苯。 描述了一种通过Cu(I)催化的乙烯基硒化物的环化反应获得2-芳基硒基苯并[ b ]硫属元素衍生物的有效方案。关键的乙烯基硒化物可以容易地由适当官能化的1,1-二溴苯乙烯制备,并且该方法允许以中等至优异的产率合成2-芳基硒基呋喃,-噻吩和-硒代苯。
