[image omitted] The lithium tert-butoxide reagent was found to promote the addition of terminal aromatic alkynes to various aromatic aldehydes. This reaction was efficiently carried out in anhydrous dimethylformamide at room temperature in air for 50min, and the corresponding propargylic alcohols were obtained in good to excellent yields (up to 95%).

the reagentless synthesis of 4,5-disubstituted triazole derivatives employing secondary propargyl alcohol as C-3 synthon and sodium azide as cycloaddition counterpart. The reaction was conducted at room temperature in an undivided cell with a constant current using a pencil graphite (C) anode and stainless-steel cathode in a MeCN solvent system. The proposed reaction mechanism was convincingly established
