13C NMR chemical shifts and 13C31P couplings are reported for triphenyl phosphate and 13 alkyl derivatives. In ortho‐alkylated materials, it is found that the upfield γ shielding effect is only operative when the carbon atom, situated γ to the exocyclic oxygen, bears at least one hydrogen. Conformational changes about the arylO bond can be monitored via the vicinal 31pOC13C couplings. Copyright
