✦ Synopsis

The two stereochemically distinct two-bond carbon-13-hydrogen coupling constants J(13C-CH), for cr-chloro~tyrene-a-'~C have been shown to be of similar magnitude but opposite sign (-6.3 and 1 5 . 6 Hz). A simple additivity relationship which adequately reproduces all the reported J(13C-CH) values for chloroethylenes has been found. * Reported resonances are for the neat liquid relative to tetramethylsilane internal reference.

Decoupling was accomplished with a Heivlett Packard 200 CD Audio Oscillator in conjunction with a Varian HA-100 spectrometer.

## Abstract The one‐bond coupling constant ^1^__J__ ^13^CH for the halogenated carbon in α‐halogenocyclohexanones is more important when the CH bond is in the equatorial then in the axial position. When a conformational equilibrium is present, the resulting coupling is a linear function of the eq
