摘要：
In a reversal of the Perlin effect, the values of 1J(C-H) for the equatorial protons at C(3)and C(6) in 1,2,4-trioxanes are less than those for the corresponding axial protons; this is ascribed to homoanomeric interactions between equatorially directed nonbonding electron pairs on oxygen and the equatorial C(3)-H or C(6)-H sigma* orbitals.
