Procedure
Phenylazide can be obtained from Sigma-Aldrich or can be synthesized by the method described in J. Biochem., 179, 397-405 (1979). A solution of tributylethynyl stannane (Sigma Aldrich; 400 mg, 1.27 mmol) in THF (4 mL) is treated with phenylazide (169 mg, 1.27 mmol), copper (I) iodide (90 mg, 0.47 mmol), and triethylamine (256 mg, 2.54 mmol) at room temperature over 48 h. The reaction is then filtered through celite to remove copper (I) iodide and chromatographed on silica in a gradient of 5-20% ethyl acetate in petrol. The second fraction is collected and concentrated in vacuo to give the 1-phenyl-4-(tributylstannyl)-1H [1,2,3]triazole as a colourless oil.
