Palladium impregnated on magnetite is an efficient, cheap and easy to prepare catalyst for the direct arylation of heterocycles. Good yields are afforded under relatively mild conditions and a broad substrate scope is evident. The catalyst is regioselective in many cases, affording arylated products, at the C2- or C3-position (depending of the heterocycle used). The methodol. can be extended to prepare chromenes through an intramol. direct arylation reaction. Some evidence is provided for two catalyst deactivation pathways, which prevents efficient recycling. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0Recommanded Product: 61150-57-0).
2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon–bromine bond is electrophilic in nature. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Recommanded Product: 61150-57-0
