Synthesis of Mesogenic Compounds, Catalyzed by Metal Complexes. II. A New Method of Synthesis of 4,4'-Dialkylbiphenyls
A new method for the synthesis of 4,4'-dialkylbiphenyls containing both n-alkyl- and 4-trans-n-alkylcyclohexyl substituents, based on highly selective reactions of monoalkylation and monoacylation of 1,4-dibromobenzene in the presence of palladium complexes is developed.
