Synergism in host–guest selectivity of picolinium chlorides by triphenylsilanol and triphenylmethanol

Author affiliations

Abstract

The host compound triphenylsilanol (TPS) has been employed in the separation of the isomers of picolinium chlorides (2PIC+, 3PIC+ and 4PIC+). By analogy with the Dutch resolution method, we employed triphenylmethanol (TPM) as an additive to TPS and thus changed the composition of the mother liquors in a systematic manner. The resulting crystals were analysed by NMR spectroscopy and X-ray diffraction. The selectivity results for TPS are 2PIC+ > 3PIC+ ≈ 4PIC+.
