Synthesis and Liquid Crystalline Properties of 1-(trans-4-Alkylcyclohexylethyl)-4-Alkyl- and -4-Alkoxy-Benzenes, Their Ketone Precursors, and Some Lateral Fluoro-Derivatives

The preparation of some 1-(trans-4-alkylcyclohexylethyl)-4-alkyl- and -4-alkoxy-benzenes, their methylenecarbonyl linked analogues and their laterally fluoro- and bromo-substituted derivatives is reported.Twenty-four inter-related compounds have been prepared and the trends in their transition temperatures are discussed.Both the melting points and clearing points for these compounds are relatively low and, in general, SB and SA phases predominate.The suitability of these compounds as additives to SC materials has been assessed using two SC hosts.Keywords: Mesogenic cyclohexylethanes, mesogenic ketones, fuoro-substitution of mesogens

SYNTHESIS OF TRANS-4-ALKYL-1-PHENYLCYCLOHEXANES AND THEIR DERIVATIVES

The alkylation of benzene by 1-alkanoyl-2-chlorocyclohexanes and 1-alkanoyl-1-cyclohexenes leads to the formation of cis- and trans-4-alkanoyl-1-phenylcyclohexanes, the yields of which increase with increase in the reaction temperature. trans-4-Alkyl-1-phenylcyclohexanes were obtained from 4-alkanoyl-1-phenylcyclohexanes and also from the products from the reaction of 4-alkylcyclohexanones with phenylmagnesium bromide.Some mesomorphous derivatives of these hydrocarbons were synthesized.

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.
