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.
我们描述了通过羟醛反应从酰基硅烷和三氟甲基三甲基硅烷合成新的偕二氟-C-甲硅烷基化羟醛。它们的脱氟甲硅烷基化产生脂肪族和脂环族2-氟-1,3-二酮。整个反应顺序可被视为一种新的补充方法,可以获得多种此类氟化 1,3-二酮。
