Abstract 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 deprotection. Rhodium‐catalysed 1,4‐addition of the arylsilane was carried out using cyclohexenone as an enone in excellent yield. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
