Novel 1,4-Palladium Migration in Organopalladium Intermediates Derived from o-Iodobiaryls
摘要:
A novel 1,4-palladium migration in organopalladium intermediates derived from o-iodobiaryls has been observed under modified Heck reaction conditions. This migration process can be switched "on" or "off" by simply choosing the appropriate reaction conditions.

of one of the strongest bonds in organic chemistry (Si–O), strategically placed at the ortho-position. In this way, the synthesis of 3-bromo-2-silylbenzofuranes is achieved in good yields. Several substituents with different electronic properties and substitution patterns are well tolerated on the tethering aromatic ring as well as a number of silyl groups on the O-atom. A preliminary mechanistic study
金-亚乙烯基配合物的高反应性,由相应的 1-溴炔烃的 [1,2]-溴转移原位产生,允许激活有机化学中最强的键之一 (Si-O),战略性地放置在邻位。这样,3-溴-2-甲硅烷基苯并呋喃的合成以良好的收率实现。几个具有不同电子特性和取代模式的取代基在束缚芳环上以及在 O 原子上的许多甲硅烷基上都具有良好的耐受性。初步的机理研究与金亚乙烯基中间体的参与是相容的。通过正交C-C键形成转化初步展示了所得支架的合成适用性。
