1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.SDS of cas: 14425-64-0

Palladium(II)-catalyzed meta-selective C-H allylation of arenes RC6H4(CH2)nXR1 [R = H, 3-Me, 3-Br, 4-F, etc.; R1 = 2-(pyrimidin-5-yl)phenoxy, 2-(pyridin-3-yl)phenoxy, 2-(8-nitroquinolin-3-yl)phenoxy, etc.; X = SO2, C(O), Si(i-Pr)2, CH2; n = 1-4] including 2-(pyrimidin-5-yl)phenyl (2S)-2-(6-methoxynaphthalen-2-yl)propanoate has been developed utilizing synthetically inert unactivated acyclic internal olefins R2CH2CH=CHCH2R3 [R2 = Me, Et, n-Pr, pentyl, etc.; R3 = Me, COOMe, [[(1S,2R,5S)-5-methyl-2-(propan-2-yl)cyclohexyl]oxy]carbonyl, etc.] as allylic surrogates. The strong σ-donating and π-accepting ability of pyrimidine-based directing group facilitates the olefin insertion by overcoming inertness of the typical unactivated internal olefins. Exclusive allyl over styrenyl products, e.g., (E)-I selectivity as well as E stereoselectivity were achieved with broad substrate scope, wide functional-group tolerance, and good to excellent yields. Late-stage functionalizations of pharmaceuticals were demonstrated. Exptl. and computational studies shed light on the mechanism and point to key steric control in the palladacycle, thus determining product selectivities. In the experiment, the researchers used many compounds, for example, 1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0SDS of cas: 14425-64-0).
