Abstract
2-Arylbenzofurans(thiophenes) were prepared through an efficient tandem elimination–intramolecular addition–Hiyama cross-coupling reaction. In the presence of tetra-(n-butyl)ammonium fluoride (TBAF), palladium(II) acetate [Pd(OAc)2] and triphenylphosphine (PPh3), the reaction of 2-(gem-dibromovinyl)phenols(thiophenols) with phenyl(trialkoxy)silanes proceeded smoothly and generated the corresponding products with good yields in one-pot. It should be noted that TBAF plays an important role in the tandem reaction.
