Palladium-catalysed silylation of aryl iodides with electron-withdrawing groups was efficiently achieved using pyridine and lithium chloride as additives and conducting the reaction at room temperature. Functionalized aryl[2-(hydroxymethyl)phenyl]dimethylsilanes were also prepared by palladium-catalysed reaction using THP-protected [2-(hydroxymethyl)phenyl]dimethylsilane as a silylating agent followed
使用吡啶和氯化锂作为添加剂并在室温下进行反应,可以有效地实现钯催化的带有吸电子基团的芳基碘化物的硅烷化。官能化的芳基[2-(羟甲基)苯基]二甲基硅烷也通过钯催化反应制备,使用THP保护的[2-(羟甲基)苯基]二甲基硅烷作为甲硅烷基化剂,然后去保护。使用环己烯酮作为烯酮以优异的产率进行芳基硅烷的铑催化1,4-加成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
