A highly efficient and selective rearrangement reaction of bromohydrins to aldehydes mediated by CF3CO2ZnEt was described. The secondary and tertiary aldehydes were prepared under mild conditions in good to excellent yields (85–99%). The scope and limitations of this rearrangement process were also investigated.
描述了由CF 3 CO 2 ZnEt介导的溴代醇对醛类的高效选择性重排反应。仲醛和叔醛是在温和的条件下以良好至极佳的收率(85–99%)制备的。还研究了这种重排过程的范围和局限性。

A reaction of methoxybenzenes or phenols with isobutyric aldehyde and 2-amino-5-nitro- or 2-amino-4-chlorobenzonitriles in concentrated H2SO4 medium was used for the preparation of new pyrrolo[3,2-l]acridinone derivatives. Analogous reactions using 2-amino-3-pyridinecarbonitrile enabled the synthesis of previously unknown benzo[b]pyrrolo[3,2-c][1,8]naphthyridinones.
