Abstract
A number of relatively volatile acetylenes RC = CH (R = aryl or hetary l) have been prepared with high yields by heating a mixture of the cor responding alcohols RC = CC(CH3)(2)OH and paraffin oil with small amou nts of powdered potassium hydroxide in vacuum. The alcohols were obtai ned by Pd/Cu-catalyzed cross coupling of aryl or hetaryl halides RX (X = Pr, in one case I) with the commercially available HC = CC(CH3)(2)O H.
