Screening of four Buchwald ligands for the cross-coupling of isomeric di-, tri- and tetrachlorobenzenes with arylboronic acids revealed that good yields of exhaustive substitution can be best provided by 2-dicyclohexylphosphino-2′-(dimethylamino) b

Methods for the replacement of chlorine atoms in polychloroarenes upon treatment with various reagents are surveyed. Considerable attention is given to catalytic methods and elucidation of the structure–reactivity relationships for polychloroarenes

The Suzuki cross-coupling with phenylboronic acid in the presence of the Pd(OAc)2/K3PO4/DMF catalytic system was successful for aryl bromides and somewhat poorer for aryl chlorides. Addition of 1,3-bis(tetrazol-1-yl)benzene or its analogs lowered the

Hexachlorobenzene and 1,2,4,5-tetrachlorobenzene react with phenylboronic acid by a C—C cross-coupling mechanism with a Pd(dba)2/P(But)3 system (dba is dibenzylideneacetone) or palladium-azole complexes as catalysts, or with organozinc compounds in

The reactions of di-, tetra-, and hexachlorobenzenes with phenylboronic acid in the presence of [Pd]-imidazolium salt-base as catalytic systems afford cross-coupling products in moderate yields. The highest conversions are attained when imidazolium s

Polychloroaromatic compounds lithiated by BunLi in THF react with several electrophilic agents of which aldehydes and epoxides seem to be the most promising from the preparative point of view.
