Abstract: I3C chemical shifts and 13C-31P nuclear spin couplings are reported for phosphorus heterocycles with exocyclic substitutions: phenyl, diphenyl, benzylphenyl, and phenyloxide. These saturated heterocycles extend from three-membered (only for the phosphine) through eight-membered rings, using di-n-butyl analogues as examples of unconstrained relatives. Sign determination for several of the 13C-31P couplings in the ...
