HYDROXIDE-CATALYZED FORMATION OF SILICON-OXYGEN BONDS BY DEHYDROGENATIVE COUPLING OF HYDROSILANES AND ALCOHOLS

The present disclosure is directed to methods for dehydrogenatively coupled hydrosilanes and alcohols, the methods comprising contacting an organic substrate having at least one organic alcohol moiety with a mixture of at least one hydrosilane and sodium and/or potassium hydroxide, the contacting resulting in the formation of a dehydrogenatively coupled silyl ether. The disclosure further described associated compositions and methods of using the formed products.

Sodium Hydroxide Catalyzed Dehydrocoupling of Alcohols with Hydrosilanes

An O-Si bond construction protocol employing abundantly available and inexpensive NaOH as the catalyst is described. The method enables the cross-dehydrogenative coupling of an alcohol and hydrosilane to directly generate the corresponding silyl ether under mild conditions and without the production of stoichiometric salt byproducts. The scope of both coupling partners is excellent, positioning the method for use in complex molecule and materials science applications. A novel Si-based cross-coupling reagent is also reported.

The effect of ring-size on the electrochemical oxidation of perethylcyclopolysilanes [(Et2Si)n]

For evaluating the net ring-size effect on the electrochemical properties of cyclic polysilanes, four perethylpolysilanes, namely octaethylcyclotetrasilane (Et2Si)4 (I), decaethylcyclopentasilane (Et2Si)5 (II), dodecaethylcyclohexasilane (Et2Si)6 (III) and tetradecaethylcycloheptasilane (Et2Si)7 (IV), were studied by cyclic voltammetry and controlled potential electrolysis. In addition, the effects of the nature of electrolyte, amount of electricity consumption and anode material on the electrolysis outcome was demonstrated for compound II.
