Below room temperature K[B(CF3)4] was found to be trimorphic according to DSC measurements, single-crystal X-ray diffraction, and vibrational spectroscopy. In its modification below –65 °C K[B(CF3)4] crystallises in the orthorhombic space group P2

The reaction of gaseous HCl with K[B(CF3)4] in diethyl ether gave the oxonium acid [H(OEt2)2][B(CF3)4] as a stable salt at room temperature. Syntheses of [Ph3C][B(CF3)4] and [Ph3C][(CF3)3BCN] were accomplished from the corresponding potassium salts a

The conformational properties and geometric structures of fluoroformic acid anhydride, FC(O)OC(O)F, have been studied by vibrational spectroscopy, gas electron diffraction (GED), single-crystal X-ray diffraction, and quantum chemical calculations (HF

Die Reaktion von M[BF4] (M = Li, K) mit (CH3)3SiCN fuhrt je nach Reaktionsdauer und Temperatur selektiv zu den gemischten Cyanofluoroboraten M[BFx(CN)4—x] (x = 1, 2; M = Li, K). Unter Verwendung von (C2H5)2O·BF3 gelingt die Synthese von (CH3)3SiNC

Tris(trifluoromethyl)borane carbonyl, (CF(3))(3)BCO, is obtained in high yield by the solvolysis of K[B(CF(3))(4)] in concentrated sulfuric acid. The in situ hydrolysis of a single bonded CF(3) group is found to be a simple, unprecedented route to a

The reductive carbonylation of IrF6 in a dilute solution of SbF5 in anhydrous HF (1:6 by volume) produces surprisingly at 25 °C and 1.5 atm CO the complex salt [Ir(CO)6][SbF6]3·4HF, while [Ir(CO)6][Sb2F11]3 is obtained in liquid SbF5 under similar
