Improved syntheses of 1-fluoropropadiene and 1,1-difluoropropadiene are presented as is the synthesis of a third reactive allene, 1,1-difluoro-3- methyl-1,2-butadiene. Gram quantities of these highly reactive fluorinated allenes may be prepared conveniently in high yield and purity. All three are reactive dienophiles and cycloadd regiospecifically using their non- fluorine-substituted double bonds.
提出了改进的1-氟丙二烯和1,1-二氟丙二烯的合成,以及第三反应性丙二烯1,1-二氟-3-甲基-1,2-丁二烯的合成。可以方便地以高收率和纯度制备克数量的这些高反应性氟化烯丙二酮。所有这三个都是反应性的亲双烯体,并使用其非氟取代的双键进行区域特异性环加成。
