General Description

Triethylmethoxysilane is a colorless liquid chemical compound with the formula C7H18OSi. It is commonly used as a crosslinking agent in the production of silicone resins and as a precursor in the synthesis of various organosilicon compounds. It is also utilized in the electronics industry as a component in the manufacturing of semiconductors and microchips. Additionally, triethylmethoxysilane is employed as a surface treatment agent for improving the adhesion and durability of coatings, adhesives, and sealants. It is known for its ability to enhance the hydrophobic and oleophobic properties of treated surfaces, making it suitable for use in water-repellent and anti-stain applications. However, it is important to handle triethylmethoxysilane with caution, as it is highly flammable and can react violently with water, creating hazardous fumes.

Accessing Two-Coordinate ZnII Organocations by NHC Coordination: Synthesis, Structure, and Use as π-Lewis Acids in Alkene, Alkyne, and CO2 Hydrosilylation

Discrete two-coordinate ZnII organocations of the type (NHC)Zn?R+ are reported, thanks to NHC stabilization. In preliminary reactivity studies, such entities, which are direct cationic analogues of long-known ZnR2 species,

Chemoselective Deoxygenation of 2° Benzylic Alcohols through a Sequence of Formylation and B(C6F5)3-Catalyzed Reduction

A sequence of formylation and B(C6F5)3-catalyzed reduction of the resulting formate with Et3SiH enables the chemoselective deoxygenation of secondary benzylic alcohols. Primary benzylic and tertiary non-benzylic alcohols are not reduced by this protocol. The formyl group fulfills a double role as activator and self-sacrificing protecting group. The deoxygenation of these formates is fast and can be carried out in the presence of other potentially reducible groups. Neighboring-group participation was found in the deoxygenation of certain diol motifs.

Catalytic Disproportionation of Formic Acid to Methanol by using Recyclable Silylformates

A novel strategy to prepare methanol from formic acid without an external reductant is presented. The overall process described herein consists of the disproportionation of silyl formates to methoxysilanes, catalyzed by ruthenium complexes, and the production of methanol by simple hydrolysis. Aqueous solutions of MeOH (>1 mL, >70 percent yield) were prepared in this manner. The sustainability of the reaction has been established by recycling of the silicon-containing by-products with inexpensive, readily available, and environmentally benign reagents.

Iron Catalyzed CO2 Activation with Organosilanes

Abstract: Iron nanoparticles generated in situ from [Fe3(CO)12] catalyzed CO2 reduction in the presence of Et3SiH as a reductant and tetrabutylammonium fluoride as a promoter to yield silyl formate (1s) under relatively mild reaction conditions. Additionally, when CO2 hydrosilylation was carried out in water, the product of CO2 reduction was formic acid. Additionally, a similar reaction using [Fe3(CO)12] as a catalytic precursor, PhSiH3 as a reductant, and CO2 in the presence of amines allowed the immediate formation of ureas at room temperature. Here, CO2 acted as a C1 building block for value-added products.
