Usage

General Description

1,1,1-triethyl-3,3,3-trimethyldisiloxane, also known as TMDSO, is a colorless and volatile liquid with a faint odor. It is primarily used as a precursor in the production of silicon dioxide thin films by chemical vapor deposition. TMDSO is also utilized as a cross-linking agent in the synthesis of silicone elastomers and resins. It is considered to be a relatively safe chemical, with low acute toxicity and good environmental compatibility. However, it should be handled with care due to its flammability and potential for irritation to the skin, eyes, and respiratory system. Additionally, proper ventilation and personal protective equipment are recommended when working with 1,1,1-triethyl-3,3,3-trimethyldisiloxane to minimize exposure.

Metal-Free Catalytic Reductive Cleavage of Enol Ethers

In contrast to the well-known reductive cleavage of the alkyl-O bond, the cleavage of the alkenyl-O bond is much more challenging especially using metal-free approaches. Unexpectedly, alkenyl-O bonds were reductively cleaved when enol ethers were reacted with Et3SiH and a catalytic amount of B(C6F5)3. Supposedly, this reaction is the result of a B(C6F5)3-catalyzed tandem hydrosilylation reaction and a silicon-assisted β-elimination. A mechanism for this cleavage reaction is proposed based on experiments and density functional theory (DFT) calculations.

Photo Lewis acid generators: Photorelease of B(C6F5)3 and applications to catalysis

A series of molecules capable of releasing of the strong organometallic Lewis acid B(C6F5)3 upon exposure to 254 nm light have been developed. These photo Lewis acid generators (PhLAGs) can now serve as photoinitiators for several important B(C6F5)3-catalyzed reactions. Herein is described the synthesis of the triphenylsulfonium and diphenyliodonium salts of carbamato- and hydridoborates, their establishment as PhLAGs, and studies aimed at defining the mechanism of borane release. Factors affecting these photolytic reactions and the application of this concept to photoinduced hydrosilylation reactions and construction of siloxane scaffolds are also discussed.
