Abstract
The E and Z configuration of enol phosphates substituted on the first carbon of the double bond are determined, in 27 cases, using [Formula: see text] coupling constants and the Tobey-Pascual substituent shielding constants method. The factors influencing [Formula: see text] and [Formula: see text] coupling constants are discussed.
