The applications of a new supported tribromide reagent based on poly(vinylbenzyltrimethylammonium tribromide) resin (Amberlite 717) were reported. This supported tribromide resin was used directly in α-bromination and α-bromoacetalization of acetophenones without any other catalyst under mild conditions. The effects of solvents and the amount of the supported tribromide resin on the reactions were investigated. Under the optimal conditions, α-bromo such as RC(O)CH2Br [R = C6H5, 2-ClC6H4, 4-PhC6H4, etc.] and α-bromoacetal such as RC(O(CH2)2O)CH2Br of acetophenones were selectively obtained in excellent yields. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)-2-phenyl-1,3-dioxolane (cas: 3418-21-1Product Details of 3418-21-1).
2-(Bromomethyl)-2-phenyl-1,3-dioxolane (cas: 3418-21-1) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Dioxole functionalized metal-organic frameworks have also been recently reported.Product Details of 3418-21-1
