Insertion of Dichlorocarbene into C-B Bond of Borinates underLiquid-Liquid Phase Transfer Catalysis Conditions: A Conve-nient Preparation of Unsymmetrical Ketones

摘要

Unsymmetrical ketones were conveniently prepared from the unsymmetrical diorganyl borinates via the insertion ofdichlorocarbene into C-B bond under liquid-liquid phase transfer catalysis conditions and oxidation with alkaline hydro-gen peroxide in 35-67% yields.
