Usage

General Description

1-Bromo-2-(4-bromophenyl)benzene is a chemical compound that has two bromine atoms each bound to two different benzene rings, one of which is in the para-position of the second ring. 1-bromo-2-(4-bromophenyl)benzene, characterized by its molecular formula C12H8Br2, has a molar mass of around 309.01 g/mol. It is typically sold as an off-white or light yellow crystalline powder. As an aromatic halogen compound, it is often used in organic chemistry reactions, behaving as an electrophile and subject to many substitution and addition reactions. Like many brominated aryl compounds, this substance should be handled with caution, as it can be a skin irritant and may have other health risks when excessively exposed to it.

Manganese(III) acetate-mediated oxidative coupling of phenylhydrazines with benzene: A novel method for biaryl coupling

The reaction of phenylhydrazines with benzene in the presence of manganese(III) acetate affords biaryls in good yields. The same reaction was carried out with similar oxidants, such as CoIII, CeIV and PbIV; among these oxidants MnIII acetate shows higher efficiency and selectivity.

PALLADIUM(II)-CATALYZED OXIDATIVE COUPLING OF ARENES BY THALLIUM(III)

Oxidation of benzenes with electron-donating and moderate electron-withdrawing substituents by thallium(III) trifluoroacetate in the presence of catalytic amounts of palladium(II) acetate affords biaryls in good yields.The GLC study of the isomer distribution has shown that 4,4'-biaryls are the major products.Thus, the 4,4'-biaryls can be easily isolated either by recrystallization or column chromatography.The competitive experiments and kinetic study using arenes and arylthallium derivatives as starting materials as well as quenching experiments have demonstrated the first step of the reaction to be fast thallation of arene to form arylthallium intermediate ArTl(OOCCF3)2.The latter undergoes the rate-determining transmetallation step reacting with monomeric complex Pd(OAc)2, which is formed upon depolymerization of trimer Pd3(OAc)6.Subsequent fast decomposition of arylpalladium species gives the final reaction products.The thallation of arene and substitution of TlIII for PdII in ArTl(OOCCF3)2 are characterized by the slopes of Hammet plots of -5.6 (?+) and -3.0 (?), respectively.
