Synthetic Route of C9H11Br. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-(Bromomethyl)-4-ethylbenzene, is researched, Molecular C9H11Br, CAS is 57825-30-6, about Tandem catalytic C(sp3)-H amination/sila-Sonogashira-Hagihara coupling reactions with iodine reagents. Author is Buendia, Julien; Darses, Benjamin; Dauban, Philippe.
A new tandem C-N and C-C bond-forming reaction has been achieved through RhII/Pd0 catalysis. The sequence combines a catalytic C(sp3)-H nitrene insertion with a palladium-catalyzed C-C cross-coupling to afford complex nitrogenous mols., e.g., I, with very good yields and complete stereoselectivity. The sequence first involves an iodine(III) oxidant, then the in situ generated iodine(I) byproduct is used as a coupling partner. The synthetic value of iodoarenes produced in trivalent iodine reagent mediated oxidations has been demonstrated.
