Phmgbr is an organometallic compound
WebbAbstract. Nickel-catalyzed asymmetric α-heteroarylation of ketones with fluorinated heteroarenes is reported via C–F bond activation. A series of ketones and 2-fluoropyridine derivatives with different functional groups proceed well to provide the corresponding products containing all-carbon quaternary stereocenters in good yields (up to 99% yield) … Phenylmagnesium bromide, with the simplified formula C 6H 5MgBr, is a magnesium-containing organometallic compound. It is commercially available as a solution in diethyl ether or tetrahydrofuran (THF). Phenylmagnesium bromide is a Grignard reagent. It is often used as a synthetic equivalent for the phenyl "Ph " synthon.
