The ethyl magnesium bromide was obtained starting from 0.24 g of Mg (10 −2 mol) and 0.75 ml of bromoethane (10 −2 mol) 0.96 g (10 −2 mol) of 1-heptyne in 20 ml of ether was added dropwise at room temperature and then heated under reflux for 1 h. After cooling to 0°C, 1.12 g (10 −2 mol) of trifluoromethylketone in 10 ml of ether was added dropwise and the mixture was stirred 1 h. The reaction mixture was poured onto ice and neutralized. After classical workup ...
