Silicatein-? (Sil?), a hydrolytic enzyme derived from siliceous marine sponges, is one of the few enzymes in nature capable catalysing metathesis silicon–oxygen bonds. It therefore interest as possible biocatalyst for synthesis organosiloxanes. To further investigate substrate scope this enzyme, series condensation reactions with variety phenols and aliphatic alcohols were carried out. In gener...

The field of organocatalysis has blossomed over the past few decades, becoming an alternative to transition-metal catalysis or even replacing the realm of transition-metal catalysis. However, a truly powerful organocatalyst with a high turnover number (TON) and turnover frequency (TOF) while retaining high enantioselectivity is yet to be discovered. Similar to metal catalysis, extremely low cat...

Interlayer silylation of layered sodium octosilicate (Na-Oct) with various organoalkoxysilanes was conducted using hexadecyltrimethylammonium ion-exchanged (C16TMA-Oct) as an intermediate in the presence or absence tetrabutylammonium fluoride (TBAF). The degree increased by adding TBAF. It is suggested that F− ions perform a nucleophilic attack on alkoxysilanes, which promotes reaction. C16TMA-...

Aromatic organosilanes bearing C(sp2)–Si bonds have found increasing applications across the chemical science, yet are mostly produced by atom-uneconomical stoichiometric procedures. Catalytic alternatives using hydrosilanes as silicon sources also been described, but they display unfavorable thermodynamics and based on expensive catalytic systems, often derived from noble metals, or lack gener...
