Silylation of aryl bromides with disilanes of type {[2- (PGOCH2)C6H4]Me2Si}2 (PG: protecting group) successfully takes place in the presence of a Pd/Ruphos or Davephos/CuI catalytic system to afford HOMSi reagents containing various functional groups in good yields. BisHOMSi reagents were also prepared directly from the corresponding arylene dibromides.

Lewis acid cocatalysts such as organoaluminum and-boron compounds dramatically improve the efficiency of the nickel-catalyzed arylcyanation of alkynes. Electron-rich aryl cyanides, which exhibit poor reactivity in the absence of Lewis acids, smoothly unde

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, 2008.
