Reactions of perfluoroalkylacetones with nucleophilic reagents

The interaction of 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 β-diketones under mild conditions. Perfluoroalkylacetones react with sodium alkoxides to give compounds of formula RFC(OR)2CH2COCH3, whose acidic hydrolysis also results in β-diketones.

Regioselective synthesis of 4-alkyl- and 4-aryl-6-(perfluoroalkyl)salicylic acid derivatives by formal [3+3] cyclocondensation of 1,3-bis(silyloxy)-1,3-butadienes with 3-silyloxy-1-(perfluoroalkyl)prop-2-en-1-ones

4-Alkyl- and 4-aryl-6-(perfluoroalkyl)salicylic acid derivatives were regioselectively prepared by [3+3] cyclization of 1,3-bis(silyl enol ethers) with 3-silyloxy-1-(perfluoroalkyl)prop-2-en-1-ones.
