Triarylphosphines containing 4-piperidinophenyl rings are conveniently prepared by PO-activated nucleophilic aromatic substitution of fluorine by piperidine and subsequent reduction of the phosphite oxides.The UV spectra of the 4-piperidinophenyl-phosphorus compounds closely resemble those of the analogous dimethylanilines.Spectroscopic substituent constants are obtained by application of the Doub-Vandenbelt equation.
