실험 절차
1-hexene (6.2 g, 76 mmol) and n-butyllithium (52 ml, 1.5 M in hexane) and trifluoroacetaldehyde (7 g, 71 mmol) were reacted 3 hours under the action of ultrasonic irradiation (as generated by a commercially available ultrasonic cleaner 220H manufactured by Branson Cleaning Equipment Company). The reaction mixture was poured into aqueous 2% HCl solution and diethyl ether was used for extraction of the oily layer. The extracts were then distilled to give 1,1,1-trifluoro-3-octyne-2-ol (b.p.: 83-85° C./21 mmHg) in a yield of 72%. This hydroxyalkyne gave the following analytical data:
