General Description

Acetoxymethyltriethoxysilane is a chemical compound used as a crosslinking agent and adhesion promoter in various applications. It belongs to the class of silane compounds and is typically employed in the production of silicone rubbers, sealants, and adhesives. The presence of acetoxymethyl and triethoxy groups in its structure allows for the silane to act as a coupling agent, enhancing the bonding between organic and inorganic materials. Additionally, the compound is known for its water-repellent properties, making it a valuable ingredient in the manufacturing of water-resistant coatings and sealants. Overall, acetoxymethyltriethoxysilane is a versatile chemical that is widely used in the construction, automotive, and electronics industries for its adhesive and sealing properties.

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
