During the prepn. of AsBr4+[Al(OR)4]-, the novel carbocation CS2Br3+ was synthesized by reaction of AsBr3, Br2, CS2, and Ag[Al(OR)4] (R=C(CF3)3). CS2Br3+ [Al(OR)4]- was characterized by its crystal structure, NMR and IR spectroscopy, and quantum chem. calc ...
The reaction of pyrrole-2,5-dicarbaldehyde (1) with o-phenylenediamine (2) in anhyd. EtOH afforded a [1+1]-condensation product, viz., Schiff's base. The structure of the latter was established by NMR spectroscopy and x-ray diffraction anal. The reaction o ...
Near-infrared emission from atmospheric OH radicals is known to severely affect astronomical observations. Until now, only complex dispersive instruments were partially capable of removing this unwanted background, which is composed of hundreds of narrow e ...
An (arene)RuCl2 complex with a methacrylate side chain (2) has been prepared in two steps using commercially available starting materials. This complex reacts with PPh3, pyridine, or toluidine to give the corresponding mononuclear adducts (3-5). The s ...
The hydrogenation of benzene and other arenes under aqueous-organic biphasic conditions is evaluated using the ruthenium complexes Ru(eta(6)-C10H14)(pta)Cl-2 (pta=1,3,5-triaza-7-phosphaadamantane), Ru(eta(6)-C10H14)(tppts)Cl-2 (tppts=tris-3-sulfonatophenyl ...
The molecular forms of LiF, LiFHF and Na2SiF6 have been stabilized using trinuclear metallamacrocyclic complexes of (cymene)Ru-II, (Cp*)Rh-III and (Cp*)Ir-III as specific receptors. The host-guest complexes were characterized by NMR spectroscopy and single ...
Hexafluoro-2-butyne, CF(3)Cequivalent toCCF(3), reacts with the triangulo-clusters [Pt-3 (mu-CO)(3)(PR3)(3)] to give the diplatinum(o) compounds [Pt-2(CO)(2)(PR3)(2)(mu-eta(2):eta(2)-CF(3)Cequivalent toCCF(3))] {PR3=PPh3 (1), PBzPh(2) (2), PCy3 (3), (PPr3) ...
A generic method is described for the reversible immobilization of polyhistidine-bearing polypeptides and proteins on attenuated total reflecting (ATR) sensor surfaces for the detection of biomol. interactions by FTIR spectroscopy. Nitrilotriacetic acid (N ...
PX4+[Al(OR)4]- (X = I: 1a, X = Br: 1b) was prepd. from X2, PX3, and Ag[Al(OR)4] [R = C(CF3)3] in CH2Cl2 at -30 Deg in 69-86% yield. P2X5+ salts were prepd. from 2PX3 and Ag[Al(OR)4] in CH2Cl2 at -30 Deg yielding almost quant. P2X5+[Al(OR)4]- (X = I: 3a, X ...
Mineral inclusions in Sao Luiz diamonds have been characterized using angle dispersive X-ray diffraction and Raman spectroscopy. We identified two different garnet phases coexisting with an omphacitic pyroxene. They represent disintegration products of a f ...
