BF3·OEt2-mediated cross-coupling of (SnMe3)2 with aryl triazene offers a new strategy for the synthesis of aryl stannane. A variety of synthetically useful aryl trimethylstannanes were produced in moderate to good yields with this metal-free approach. One-pot sequential Stille cross-coupling with different aryl bromides provides a short entry to both symmetrical and unsymmetrical biaryl compounds.
BF 3 ·OEt 2介导的(SnMe 3)2与芳基三氮烯的交叉偶联为芳基锡的合成提供了新的策略。使用这种无金属方法,可以以中等到良好的产率生产各种合成有用的芳基三甲基锡烷。与不同芳基溴化物的一锅式顺序Stille交叉偶联为对称和不对称联芳基化合物提供了一个简短的入口。
