α-Bromoketals and acetals are important synthetic precursors in organic synthesis. In this work, some new α-bromoketals are synthesized by the reaction of aryl Me ketones with diols in the presence of 1,8-diazabicyclo[5.4.0] undec-7-ene (DBU) hydrobromide-perbromide in good isolated yields. The latter compound converts aldehydes to acetals and serves as a new and efficient reagent for the synthesis of acetals. Comparative studies of the preparation of α-bromoketal and acetals using some reported methods vs. the present method show that DBUH-Br3 is one of the most efficient reagents for the preparation of these compounds Conversion of carbonyl compounds to corresponding α-bromoketals and acetals in the presence of DBUH-Br3 under microwave irradiation is also described. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)-2-phenyl-1,3-dioxolane (cas: 3418-21-1Recommanded Product: 2-(Bromomethyl)-2-phenyl-1,3-dioxolane).
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. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Recommanded Product: 2-(Bromomethyl)-2-phenyl-1,3-dioxolane
