摘要：

A stereocontrolled synthesis of all-cis-1,2,4,5- tetrafluoro-3-phenylcyclohexane is developed as the first functionalised example of this polar cyclohexane motif. The dipolar nature of the ring, arising due to two 1,3-diaxial CF bonds, is revealed in the solid-state (X-ray) structure. The orthogonal conformation of the aryl and cyclohexyl rings in all-cis-1,2,4,5-tetrafluoro-3-phenylcyclohexane, and in an ortho-nitro derivative, result in intramolecular (1h)J(HF) and (2h)J(CF)NMR couplings relayed through hydrogen bonding. The aryl group of all-cis-1,2,4,5-tetrafluoro-3-phenylcyclohexane is elaborated in different ways to demonstrate the versatility of this compound for delivering the motif to a range of molecular building blocks.
