Abstract
The two 3,7-disubstituted diquinanes 510 and 511 have been investigated by single crystal X-ray diffraction techniques and shown to possess the illustrated W conformation [224]. Nonbonded H----H distances of 1.754(4) and 1.713(3) Å have been measured by low-temperature neutron diffraction experiments for 512 and 513 [225]. At 2.921(4) Å, the distance between the pairs of double bonds in 514 is also quite short [226].KeywordsCrystal Structure DataForce Field CalculationEmpirical Force FieldCentral Double BondDouble Quantum CoherenceThese keywords were added by machine and not by the authors.
