Stage #1: at 40℃; for 2 h; Schlenk technique
Stage #2: With hydrogenchloride In waterSchlenk technique
General procedure: The terminal alkyne (1.0 mmol) was added to a mixtureof HSi(OEt)2Me (5.0 mmol) and KOtBu (1.5 mmol) in a10 mL Schlenk tube with a magnetic stirrer. The Schlenktube was evacuated and back-filled with CO2 for 3 times.After a CO2 ballon was connected, the reactor was moved toa water bath of 40 °C. After being stirred for 2 h, the reactionmixture was diluted with water (30 mL), and was extractedwith CH2Cl2 (3×10 mL). The aqueous layer was acidifiedwith aqueous HCl (6 M) and then extracted with diethylether (5×20 mL). The combined organic extracts were driedover Na2SO4 and concentrated under vacuum to give the purepropiolic acid (such as compound 3-phenylpropiolic acid(3a): 98percent).

YieldReaction ConditionsOperation in experiment
64% With copper(l) iodide In methanol; N,N-dimethyl-formamide at 100℃; for 12 h; Inert atmosphere To a solution of 3-ethynylpyridine (0.20 g, 1.94 mmol, 1 eq) in DMF/MeOH 9:1 (4.0 mL), CuI (0.02 g, 0.097 mmol, 0.05 eq) and trimethylsilylazide (0.38 mL, 2.91 mmol, 1.5 eq) were added.
The reaction was heated at 100 °C for 12 h under nitrogen.
After cooling, the reaction was filtered off through a Celite pad and washed with EtOAc.
Evaporation of the solvent gave a residue which was purified by column chromatography, using PE/EtOAc 3:7 and then EtOAc to give 2 as a white solid after crystallization with EtOAc (0.18 g, 64percent).
