Abstract: | The reaction between Grignard reagents and perfluoroacid fluorides provides a convenient synthesis procedure for ketones RfORfC(O)R′, where RfORf is perfluoroalkylether group and R' is either an aromatic or aliphatic group. Reaction temperature is an important factor in producing higher yields of ketones. Meta and para-bromophenyl Grignard reagents, which thus far have not been prepared as pure mono Grignards, present secondary competing reactions which detract from their synthetic utility. |
