摘要：

4-Fluoro-2-butynal FCH2CCCHO (5) is prepared in good yield by formolysis of the corresponding fluoro-acetal FCH2CCCH(OEt)2 (4). The dienophilic properties of (5) are investigated towards 2,3-dimethyl-l,3-butadiene (6). cyclopentadiene (7) and 1,3- cyclohexadiene (8) [possible hazards during the reaction with (6)]. The results emphasize the activating effect of the FCH2 group on the electrophilic character of the -CC bond in (5). © 1990.
