Stille coupling under palladium catalysis between some substituted aryl compounds and benzyltributyltin compounds generated through sonicated Barbier reaction in a very short time reaction and excellent yield. The study reported below compares different methods to optimize the synthesis of usually unstable benzyltin derivatives and is another contribution to the investigation of Csp(3)-Csp(2) coupling
在这里,我们介绍了在超声催化的巴比尔反应中,在很短的时间内就通过超声斯蒂勒偶合在钯催化下,在一些取代的芳基化合物和苄基三丁基锡化合物之间获得的各种二芳基甲烷的制备方法。以下报道的研究比较了优化通常不稳定的苄基锡衍生物合成的不同方法,这是对涉及苄基-芳基试剂的Csp(3)-Csp(2)偶联过程研究的另一贡献。通过某些二芳基甲烷的氧化,可以容易地以非常好的收率制备取代的羧化二苯甲酮。
