  摘要：

  We describe the synthesis of 2,2-difluoro-1,5-diketones in a one-pot procedure from an acylsilane and trifluoromethyltrimethylsilane, via reaction of difluoroenoxysilanes and enones under electrophilic activation. These diketones are interesting building blocks for the synthesis of gem-difluoro enones or substituted fluorophenols, depending on the annulation conditions. The annulation proceeds with complete regioselectivity controlled by the fluorine substitution. (C) 1998 Elsevier Science Ltd. All rights reserved.
