We describe the synthesis of new gem-difluoro-C-silylated aldols from acylsilanes and trifluoromethyltrimethylsilane via an aldol reaction. Their defluorosilylation gives aliphatic and alicyclic 2-fluoro-1,3-diketones. The overall reaction sequence can be considered as a new complementary method giving access to a wide variety of such fluorinated 1,3-diketones.
