چکیده
The crystal structure of the title compound, C(64)H(52)Br(4)O(8)·1.31C(3)H(6)O·0.69CHCl(3), is described. The structure has been reported previously [Bryant, Blanda, Vincenti & Cram (1991). J. Am. Chem. Soc.113, 2167-2172]; however, the lower data acquisition temperature results in an improved refinement model. In addition, the presence of residual acetone and (disordered) chloro-form within the mol-ecular structure of the title compound represents a new clathrate of the title compound. One half of the resorcin[4]arene cavitand mol-ecule appears in the asymmetric unit; the complete resorcin[4]arene cavitand structure was generated across a mirror plane.

The title compound, C(68)H(56)O(16), was synthesized as a novel synthetic inter-mediate towards deeper and more elaborate resorcin[4]arene cavitands. The structure is the first reported example of a resorcin[4]arene cavitand bearing aromatic aldehyde functional groups at the extra-annular rim of the mol-ecule. The 2-formyl-phen-oxy residues are found to assume two different orientations above t...

The title compound, C(68)H(64)O(8)·C(4)H(8)O(2), is a new resorcin-[4]arene cavitand synthetic precursor, obtained by alkyl-ation of a previously reported resorcin[4]arene. The additional alkyl bridges significantly rigidify the structure and enforce a 'bowl' shape on the mol-ecular cavity. In the crystal structure, the mol-ecule lies on a crystallographic mirror plane, and a single ethyl aceta...
متن کاملResorcin[4]arene cavitand with 1,3,2-benzodiazaborolyl walls as a fluorescence receptor for ammonium cations.
Resorcin[4]arene cavitand 1 with 1,3,2-benzodiazaborolyl walls was newly synthesized. It showed a large blue shift in the fluorescence spectra upon selective complexation with alkyltrimethylammonium salts in CH(2)Cl(2)-DMSO (9 : 1 v/v); this shift was detectable with the naked eye.

The partially bridged resorcin[4]arene cavitand featuring a cleft-shaped recognition site formed by two anti-quinoxaline bridges and four convergent HO-groups was prepared in three steps and characterised by X-ray crystallography; cavitand was found to be a selective receptor for steroidal substrates in CDCl3, with the best binding observed for steroids with a flat A-ring and two H-bonding site...
متن کاملA deep tetranuclear metallo-cavitand with bis(aryl) palladium bridges.
A neutral metallo-cavitand based on cis bis-perhaloaryl Pd(II) bridges co-ordinated at the corners of a deep calix[4]arene. Both the metallo-cavitand and its inclusion complexes with other calix[4]arenes were investigated by means of (1)H and (19)F NMR experiments.
