Usage

General Description

Dodecyldimethylchlorosilane is an organosilicon compound that is commonly used as a chemical intermediate and in surface treatment applications. It is a clear, colorless liquid with a pungent odor and is highly reactive with water, alcohols, and acids. DODECYLDIMETHYLCHLOROSILANE is primarily used as a silane coupling agent in the production of adhesives, sealants, and coatings, as well as in the modification of surfaces to improve adhesion and wetting properties. It is also utilized in the synthesis of silicone polymers and as a precursor in the production of specialty chemicals. Dodecyldimethylchlorosilane is considered hazardous due to its flammability and corrosive nature, and proper safety measures should be taken when handling and storing this chemical.

A General and Selective Synthesis of Methylmonochlorosilanes from Di-, Tri-, and Tetrachlorosilanes

Direct catalytic transformation of chlorosilanes into organosilicon compounds remains challenging due to difficulty in cleaving the strong Si-Cl bond(s). We herein report the palladium-catalyzed cross-coupling reaction of chlorosilanes with organoaluminum reagents. A combination of [Pd(C3H5)Cl]2 and DavePhos ligand catalyzed the selective methylation of various dichlorosilanes 1, trichlorosilanes 5, and tetrachlorosilane 6 to give the corresponding monochlorosilanes.

Trialkylsilylethynyl-substituted triphenylenes and hexabenzocoronenes: Highly soluble liquid crystalline materials and their hole transport abilities

Four triphenylene (TP) and four hexa-peri-hexabenzocoronene (HBC) derivatives with trialkylsilylethynyl groups were prepared and characterized by differential scanning calorimetry, polarizing optical microscopy, and X-ray diffraction measurements. All compounds were highly soluble in less-polar organic solvents and exhibited a columnar phase, Colh or Colr for the TPs, and Colh for the HBCs. The hole transport ability in the HBCs' columnar phase, 0.4-1.5×10-3 cm2 V-1 s-1 at 40-180°C, and its temperature dependence were determined by the time-of-flight method using a solution technique.

The carbon-silicon bond cleavage of organosilicon compounds in supercritical water

Arylsilanes, alkenylsilanes, allylic silanes, and alkylsilanes were found to undergo extremely facile and rapid C-Si bond cleavage in supercritical water. Rapid C-Si bond cleavage occurred even with robust unactivated tetraalkylsilanes. The control experiments revealed the dramatic difference between the supercritical and subcritical conditions, and that between supercritical water and supercritical methanol, attesting to a unique reactivity of supercritical water in C-Si bond cleavage. It was also found that acids, such as HCl, HBr, and H2SO4, promote C-Si bond cleavage in supercritical water.
