General Description

Chloromethylmethyldiisopropoxysilane is a chemical compound with the molecular formula C9H23ClO2Si. It is a silane-based compound that contains a chloromethyl group and two diisopropoxy groups attached to a silicon atom. This chemical is used as a coupling agent or crosslinking agent in various industrial applications, such as in the production of adhesives, coatings, and sealants. Chloromethylmethyldiisopropoxysilane can also be used as a surface modifier for materials such as glass, metals, and polymers, where it acts as a water repellent and improves adhesion. Additionally, it can be used as a precursor for the synthesis of other organosilicon compounds due to its reactive nature. However, it is important to handle this chemical with caution as it is toxic and requires proper safety measures during handling and storage.

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
