摘要：

Terminal alkynes were readily obtained via the reaction of alkynoic acids withN,N,N',N'-teramethylethylenediamine (TMEDA) in DMSO at 65 degrees C for 12 h. This method gave good yields and showed high functional group tolerance. In addition, deuterated terminal alkynes were formed in good yields when alkynoic acids were treated with D2O prior to the reaction with TMEDA.
