NoteFacile hydroboration of (Z)-1-trimethylsilyl-1-alkenes with Dichloroborane (cas 13701-67-2)–dioxane complex: An easy access to gem-dimetalloalkanes containing boron and silicon

(Z)-1-trimethylsilyl-1-alkenes easily prepared by the hydroboration of the corresponding 1-trimethylsilyl-1-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 °C for half an hour to provide the corresponding gem-dimetalloalkanes containing boron and silicon. These α-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 α-trimethylsilyl group in 78–88% isolated yields.
