Dimesitylboron stabilised carbanions react with oxiranes to give products that can be oxidised to 1,3-diols. The reactions are, in general, under steric rather than electronic control, and proceed smoothly for all but tetrasubstituted oxiranes. Some unusual stereoselective effects have been observed.
Dimesitylboron稳定的碳负离子与环氧乙烷反应,生成可以氧化为1,3-二醇的产物。该反应通常在空间而不是电子控制下进行,并且对于除四取代的环氧乙烷外的所有反应均平稳进行。已经观察到一些不同寻常的立体选择性作用。
