摘要
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 by de-protection. Rhodium-catalysed 1,4-addition of the arylsilane was carried out using cyclohexenone as an enone in excellent yield.
