CAS 2227-29-4: Chlorobis(1-methylethyl)silane

Diisopropyl Chlorosilane

Chlorodiisopropylsilane is a reactive functional group with a carbonyl group. It reacts with hydrocarbons and other organic compounds to form chlorosilanes with the elimination of hydrogen chloride gas. This compound is used as a solvent in the preparation of silicon nanowires, cyclopentane rings, and eribulin. Chlorodiisopropylsilane is also used as a precursor to other silicon-containing molecules including silicon monomers, which are precursors to polymers.

Specialty Silicon-Based Blocking Agent Used as a protecting group for reactive hydrogens in alcohols, amines, thiols, and carboxylic acids. Organosilanes are hydrogen-like, can be introduced in high yield, and can be removed under selective conditions. They are stable over a wide range of reaction conditions and can be removed in the presence of other functional groups, including other protecting groups. The tolerance of silylated alcohols to chemical transformations summary is presented in Table 1 of the Silicon-Based Blocking Agents brochure. Tri-substituted Silane Reducing Agent Organosilanes are hydrocarbon-like and possess the ability to serve as both ionic and free-radical reducing agents. These reagents and their reaction by-products are safer and more easily handled and disposed than many other reducing agents. The metallic nature of silicon and its low electronegativity relative to hydrogen lead to polarization of the Si-H bond yielding a hydridic hydrogen and a milder reducing agent compared to aluminum-, boron-, and other metal-based hydrides. A summary of some key silane reductions are presented in Table 1 of the Silicon-Based Reducing Agents brochure.
