Abstract

The sulfamide derivative of triphenylmethanol, 3-[hydroxy(diphenyl)methyl]benzenesulfonamide (H2NSO2Ph)Ph2COH 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 Ph3COH, Ph3CNH2 and Ph3CNH3·NCS, while (H2NSO2Ph)Ph2COH forms the complex exclusively with 18-crown-6 (18C6). The triphenylammonia trifluoroacetate, Ph3CNH3·CF3COO, selectively forms the complex only with 2-methoxyethanol. The crystalline products of the compositions (Ph3COH)2·12C4, (Ph3CNH2)2·12C4, (Ph3CNH3·NCS)2·12C4, [(H2NSO2Ph)Ph2COH]2·18C6 and Ph3CNH3·CF3COO CH3OCH2CH2OH were obtained and studied by X-ray single crystal diffraction.
