A new synthetic protocol for the one-pot, stereoselective synthesis of 1,3,5-tris[(E)-4-halostyryl]benzene and 1,2,4,5-tetrakis[(E)-4-halostyryl]benzene derivatives as stilbenoid dendrimer cores via palladium-catalyzed Hiyama cross-coupling of aryl tri- or tetrahalides with 1,3-bis[(E)-4-halostyryl]disiloxanes is described.
1,3,5-三[(E)-4-卤代苯乙烯基]苯和1,2,4,5-四[(E)-4-卤代苯乙烯基]苯的一锅立体选择性合成新合成方案描述了通过钯催化的 Hiyama 交叉偶联芳基三或四卤化物与 1,3-双[(E)-4-卤代苯乙烯基]二硅氧烷作为芪类树枝状聚合物核的衍生物。
