perfluoroalkylacetones of formula RFCH2COCH3 (RF=n-C3F7, n-C4F9, n-C6F13, n-C8F17) with ammonia and primary and secondary amines has been studied. In all cases, nucleophilic reagents initially dehydrofluorinate the starting ketone, and then substitution of the vinyl fluorine atom by a nucleophile occurs to give aza analogues of β-dicarbonyl compounds RFC(NR2)=CH-C(O)CH3; their hydrolysis yields the corresponding
式R F CH 2 COCH 3(R F = n -C 3 F 7,n -C 4 F 9,n -C 6 F 13,n -C 8 F 17)的全氟烷基丙酮与氨以及伯和仲的相互作用胺已被研究。在所有情况下,亲核试剂都会先对起始的酮进行脱氟化氢,然后再用亲核试剂取代乙烯基氟原子,从而得到β-二羰基化合物R F C(NR 2)= CH-C(O)CH 3;它们的水解在温和条件下产生相应的β-二酮。全氟烷基丙酮与烷氧基钠反应,生成式R F C(OR)2 CH 2 COCH 3的化合物,其酸性水解作用还会生成β-二酮。
