The propargylation of aldehydes promoted by microwave irradiation using allenylboron compounds in a chemo- and regioselective way is described. The corresponding products were obtained in short reaction time, high yield and purity without the need of any solvent when allenylboronic acid pinacol ester was used, or using a minimal amount of acetone when potassium allenyltrifluoroborate was used.

The commercially available resin Amberlyst A-31 was efficiently used to promote the propargylation of aldehydes using potassium allenyltrifluoroborate. The method is simple and fast, and the products were obtained in short reaction times in high yields and purity at room temperature in a regio- and chemoselective manner.

In the presence of water, metallic tin and propargyl bromide reacted smoothly with aldehydes to give the corresponding homopropargyl alcohols (a) and homoallenyl alcohols (b).High chemospecifity to bifunctional carbonyl compounds containing -OH, -X and -NO2 etc. was obtained.
