Malarski, Z. published the artcileDielectric and spectroscopic studies of pentachlorophenol-amine complexes, Recommanded Product: 4-Amino-2-picoline, the publication is Journal of Physical Chemistry (1982), 86(3), 401-6, database is CAplus.
Dipole moments in CCl4, IR absorption spectra under various conditions, and UV spectra of a number of pentachlorophenol (PCP) complexes with N bases were measured over a broad ΔpKa range. From the dipole moment measurements an inversion region of ΔpKa was found for which a 50% proton transfer can be expected. The complexes from this region exhibit certain anomalies in their IR spectra, in particular a broad continuous absorption, a strong temperature effect on the absorption in the far-IR, and particular sensitivity to changes in solvent polarity. The UV spectra revealed proton-transfer equilibrium for a number of complexes, both in solutions and in the solid state.
