A good part of today's liquid crystals (LCs) for display applications are derived from the Darzens–Nenitzescu reaction which, in a one-pot-process, yields 1,4- trans -acylphenylcyclohexanes from acid chlorides, benzene, and cyclohexene. A mechanism for this process is proposed based on quantum-chemical computations. The products of this reaction can be further elaborated to all- trans -4,4′-disubstituted-[1,1′-bicyclohexane] compounds, essential components in almost all fast switching LC-mixtures. An equilibration process involving carbo-cations is used to control the diastereomer distribution. [ABSTRACT FROM AUTHOR] |
