Metal complexes of PAR, TAR and PAN.
A discussion of the problem of assignment of a pk value for the hypothetical dissociation of the o-OH proton in TAR, PAR and PAN before the P-OH proton. The view is expressed that the most reasonable choice is to use the normal pk value for this dissociation, rather than the normal pk value for the p-OH proton.
