  Facile hydroboration of (Z)-1-trimethylsilyl-1-alkenes with dichloroborane–dioxane complex: An easy access to gem-dimetalloalkanes containing boron and silicon

  摘要：

  (Z)-l-Trimethylsilyl-l-alkenes easily prepared by the hydroboration of the corresponding 1-trimethylsilyi-l-alkynes followed by protonolysis with acetic acid, readily react with dichloroborane-dioxane complex in dichloromethane for 6 h. The resulting solution is then treated with 1,3-propane diol in dichloromethane at 0 degrees C for half an hour to provide the corresponding gem-dimetalloalkanes containing boron and silicon. These alpha-trimethylsilylalkylboronate esters are purified by vacuum distillation in high yields (72-84%) and the structures of these novel intermediates are further confirmed by selective oxidation with alkaline hydrogen peroxide to provide the corresponding alcohols containing alpha-trimethylsilyl group in 78-88% isolated yields.
