HYDROXIDE-CATALYZED FORMATION OF SILICON-OXYGEN BONDS BY DEHYDROGENATIVE COUPLING OF HYDROSILANES AND ALCOHOLS
-
Paragraph 0148; 0176, (2017/02/28)
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.
N-Methylacridinium Salts: Carbon Lewis Acids in Frustrated Lewis Pairs for σ-Bond Activation and Catalytic Reductions

N-methylacridinium salts are Lewis acids with high hydride ion affinity but low oxophilicity. The cation forms a Lewis adduct with 4-(N,N-dimethylamino)pyridine but a frustrated Lewis pair (FLP) with the weaker base 2,6-lutidine which activates H2, even in the presence of H2O. Anion effects dominate reactivity, with both solubility and rate of H2 cleavage showing marked anion dependency. With the optimal anion, a N-methylacridinium salt catalyzes the reductive transfer hydrogenation and hydrosilylation of aldimines through amine-boranes and silanes, respectively. Furthermore, the same salt is active for the catalytic dehydrosilylation of alcohols (primary, secondary, tertiary, and ArOH) by silanes with no observable over-reduction to the alkanes.
