Article Description

The sulfamide derivative of triphenylmethanol, 3-[hydroxy(diphenyl)methyl] benzenesulfonamide (HNSOPh)PhCOH was synthesized and, alongside with the parent triphenylmethanol and triphenylmethylamine, was investigated for selective interactions with crown ethers of different dimensionality (12-18-membered cycles). The molecule of 12-crown-4 (12C4) appeared to be the best candidate for PhCOH, PhCNH and PhCNH·NCS, while (HNSOPh)PhCOH forms the complex exclusively with 18-crown-6 (18C6). The triphenylammonia trifluoroacetate, PhCNH·CFCOO, selectively forms the complex only with 2-methoxyethanol. The crystalline products of the compositions (PhCOH)·12C4, (PhCNH )·12C4, (PhCNH· NCS)·12C4, [(HNSOPh)Ph COH]·18C6 and PhCNH ·CFCOO CHOCHCH OH were obtained and studied by X-ray single crystal diffraction. © 2009 The Royal Society of Chemistry.
