1-(alpha-Aminoalkyl)benzotriazoles react with sodium dialkynyldiethylaluminates to give propargylic amines in excellent yields, including unsubstituted N,N-dialkyl propargylamines, which are difficult to obtain from Lithium acetylide. The reaction of alpha-benzotriazolyl alkyl ethers and sodium dialkynyldiethylaluminate in the presence of zinc iodide also gives propargylic ethers in excellent yields. Unsubstituted propargyl ethers are prepared via the desilylation of trimethylsilylpropargyl ethers.
