Synthesis and Structure of O-silylated 2-Polyfluoroacyl-cycloalkanones
摘要:
2-Acyl-cycloalkanones containing polyfluoroalkyl groups react with dichlorodimethylsilane to form the corresponding heterocyclic bis-enol derivatives. The reaction of 2-polyfluoroacylcycloalkanones with chlorotrimethylsilane leads to mixtures of the corresponding (Z)-configured O-silylethers. The silatropy process in this case is slow on the NMR time scale.

The preparation of some new perfluoroalkyl 1,3-dicarbonyl compounds is reported. The alcoholysis reaction of these 2-perfluoroalkanoylcycloalkanones in the presence or in the absence of base catalysis occurs, involving ring cleavage to yield fluorinated oxo esters.
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(silylenolethers) with 3-silyloxy-1-(perfluoroalkyl)prop-2-en-1-ones.
