Stereospecific syntheses of the cis-trans-isomer of dicyclohexano-18-crown-6 allows the K + complexation behavior of all five dicyclohexano-18-crown-6 isomers to be compared.

Chiral trans-anti-trans-dicyclohexano-18-crown-6 isomers are synthesized via a lipase-catalyzed reaction. The solidstate structure of the (S)-enantiomer is determined and compared with those reported for 18-crown-6 and trans-syn-trans-dicyclohexano-18-crown-6.

Microwave spectra of the trans-cis isomer of ethyl vinyl ether and its nine deuterated species were measured. A plausible molecular structure was obtained from the observed moments of inertia by an application of a diagnostic least-squares technique. The dipole moment and its direction were determin
