                                    An effective, convenient, and mild coupling reaction of benzylic alcohols with terminal alkynes has been developed. As an effective Lewis acid, Cu(OTF)(2)-catalyzed arylmethylation of terminal alkynes with benzylic alcohols generated the corresponding products in BrCH2CH2Br with good yields in the absence of ligand, base, and additive.
