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.

CONVENIENT SYNTHESIS OF 4-(TRANS-4 prime -N-ALKYLCYCLOHEXYL) BENZOIC ACIDS.
A convenient method of obtaining 4-(trans-4 prime -n-alkylcyclohexyl) benzoic acids from alkanoyl chlorides, cyclohexane and benzene is described. Homologous series of above mentioned acids and their nitriles with alkyl tail 2 to 10 carbon atoms were prepared and temperatures of their phase transitions were determined.
