N-(Diphenylselenio)diphenylsulfimidium tetraphenylborate.
The title compound, C24H20NSSe+.C24H20B-, exhibits disorder (S/Se scrambling) of the chalcogen sites within the S-N-Se triad. Similar disorder was observed in the bromide salt [Aucott, Bailey, Elsegood, Gilby, Holmes, Kelly, Papageorgiou & Pedron-Haba (2004). New J. Chem. pp. 959-966]. The S-N and Se-N bond lengths are 1.6735 (15) and 1.8045 (14) A, respectively. Whereas the chalcogens in the b...
متن کاملComplexation of N- Heteroaromatic Cations with Crown Ethers and Tetraphenylborate
Study was made of host-guest complexation of neutral crown ethers with fiveand six-membered Nheteroaromatic cations and purinium cation. Complexation of tetraphenylborate with selected Nheteroaromatic cations and tropylium cation also was studied. Crown ether complexes were characterized by mass spectrometric and 1H NMR spectrometric methods and by X-ray crystallography. Fast atom bombardment m...
متن کاملStructure and Molecular Motions in Rubidium Tetraphenylborate
By X-ray diffraction it was found that at 293 K the crystals of rubidium tetraphenylborate are tetragonal, space group I4̄2m, a = b = 11.212(2) Å, c = 8.098(2) Å, with 2 molecules of Rb[C24H20B] # in the unit cell. The molecular reorientations as functions of temperature were studied by H NMR. Two types of motions were detected: an anisotropic reorientation of the tetraphenylborate anions about ...
متن کاملTetraphenylborate stimulation of phospholipid labeling in goldfish brain.
The presence of tetraphenylborate (TPB, 10 -3 M to 10 -4 M) in goldfish brain articulate preparations during a 5-15 min incubation with Y-~~P-ATP or y3f; P ATP results in marked stimulation of labeling of phosphatidate and a decrease in labeling of phosphatidyl inositol phosphate. Incorporation into phosphatidyl inositol diphosphate, a minor labeled phospholipid, is also depressed by TPB. We su...
متن کاملCoordinating anions: (phosphino)tetraphenylborate ligands as new reagents for synthesis.
Anionic, electron-releasing phosphines that incorporate a borate counteranion within the ligand framework are promising reagents for organometallic catalysis. This report describes the synthesis of a new class of monodentate tertiary phosphines built upon the commonly employed tetraphenylborate anion. These new phosphines are highly stable and strongly electron-releasing and readily coordinate ...
