Effect of a phosphorus atom upon vicinal – coupling constants in pyranose derivatives having a C–P bond: Additivity rule for the effect of phosphorus substituents

Additivity constants for phosphorus were estimated for the prediction of vicinal 1H–1H coupling constants by means of an additivity rule in a series of pyranose analogs having phosphorus as the ring heteroatom. The experimental J values were well reproduced by employing the proposed additivity const
