General description
6-Chloroquinoline is a haloquinoline. Pd/C-catalyzed Suzuki-Miyaura coupling of 6-chloroquinoline with 2-(dicyclohexylphosphino)biphenyl is reported. The polarographic behavior of 6-chloroquinoline in DMF solutions and mechanism of its reduction at the dropping mercury electrode has been reported. Stability constants of molecular iodine complexes of 6-chloroquinoline in aliphatic and aromatic hydrocarbons, carbon tetrachloride, bromobenzene and chloro-substituted benzenes was investigated by spectrophotometric methods.
The standard molar enthalpy of formation of 6-chloroquinoline has been derived from the standard molar enthalpy of combustion and was evaluated in terms of molecular structure. Its arylation reaction with diamine derivatives of adamantanes in the presence of palladium catalyst has been reported to afford N,N′-diaryl derivatives.
Application
6-Chloroquinoline may be used in the synthesis of 3-methyl-3H-imidazo[4,5-f]quinolin-2-amine. It may be used as catalyst for high yield preparation of ethoxycarbonyl isothiocyanate.

A phosphine ligand, such as PPh3 or 2-(dicyclohexylphosphino)biphenyl, is essential for the Pd/C-catalyzed Suzuki-Miyaura coupling of halopyridines and haloquinolines, although it has been reported that the reaction of phenyl chlorides can be catalyzed by nonprereduced Pd/C without any additives.
