title: An efficient tandem elimination-cyclization-desulfitative arylation of 2-(gem-dibromovinyl)phenols(thiophenols) with sodium arylsulfinates.
abstract: An efficient tandem elimination-cyclization-desulfitative arylation of 2-(gem-dibromovinyl)phenols(thiophenols) with sodium arylsulfinates has been developed. In the presence of TBAF-PdCl(2)-Cu(OAc)(2)-NEt(3), the reactions generated 2-arylbenzofurans(thiophenes) with good yields in one-pot under ligand-free conditions.
