Usage

General Description

CHLOROMETHYLTRIISOPROPOXYSILANE 96 is a chemical compound used in various industrial applications, particularly in the production of silicone polymers. It is a clear, colorless liquid with a pungent odor, and it is highly flammable and reactive. CHLOROMETHYLTRIISOPROPOXYSILANE 96 is commonly used as a crosslinking agent in silicone rubber production, as well as a coupling agent in the formulation of adhesives, sealants, and coatings. It is also utilized in the manufacturing of electronic components and in the modification of surfaces to improve adhesion and moisture resistance. Additionally, CHLOROMETHYLTRIISOPROPOXYSILANE 96 is considered hazardous and should be handled with caution, as it may cause irritation to the skin, eyes, and respiratory system upon contact or inhalation.

Synthesis of 2,2,5,5-Tetrasubstituted 1,4-Dioxa-2,5-disilacyclohexanes via Organotin(IV)-Catalyzed Transesterification of (Acetoxymethyl)alkoxysilanes

(Acetoxymethyl)silanes 2, 7 a-c, and 10 a-c with at least one alkoxy group, of the general formula (AcOCH2)Si(OR)3-n(CH 3)n (R: Me, Et, iPr; n=0, 1, 2), were synthesized from the corresponding (chloromethyl)silanes 1, 6 a-c, and 9 a-c by treatment with potassium acetate under phase-transfer-catalysis conditions. These compounds were found to provide 2,2,5,5-organo-substituted 1,4-dioxa-2,5- disilacyclohexanes 3, 8 a-c, and 11 a-c if treated with organotin(IV) catalysts such as dioctyltin oxide. The reaction proceeds through transesterification of the acetoxy and alkoxy units followed by ring-closure to form a dimeric six-membered ring. The corresponding alkyl acetates are formed as the reaction by-products. With these mild conditions, the method overcomes the drawbacks of previously reported synthetic routes to furnish 2,2,5,5-tetramethyl-1,4-dioxa-2, 5-disilacyclohexane (3) and even allows the synthesis of 1,4-dioxa-2,5- disilacyclohexanes bearing hydrolytically labile alkoxy substituents at the silicon atom in good yields and high purity. These new materials were fully characterized by NMR spectroscopy, elemental analysis, mass spectrometry, and X-ray analysis (trans-8 a). Tin makes the ring! Easily accessible (acetoxymethyl)silanes with at least one alkoxy group give 2,2,5,5-organo- substituted 1,4-dioxa-2,5-disilacyclohexanes (see figure) in good yields and high purity when treated with organotin(IV) catalysts. The mild reaction conditions even allowed the synthesis of cyclic silanes with hydrolytically labile alkoxy substituents. Copyright
