Perfluorosalkyl Tellurium Compounds: Oxidation of (CF3)2Te; Preparations and Properties of (CF3)2TeCl2, (CF3)2TeBr2, (CF3)2Te(ONO2)2, and (CF3)2TeO From the oxidation of (CF3)2Te with Cl2, Br2, O2, and ClONO2 the new trifluoromethyl tellurium compounds (CF3)2TeCl2, (CF3)2TeBr2, (CF3)2TeO, and (CF3)2Te(ONO2)2 are prepared. The 19F, 13C and 125Te n.m.r. spectra, the vibrational and mass spectra as well as the chemical properties of these compounds are described. By variation of the reaction conditions CF3TeCl3 and CF3TeBr3 are also formed. It has not been possible to isolate (CF3)2TeI2, but there is some evidence that it is formed as an intermediate. (CF3)2Te reacts with ozone to a very unstable compound, which decomposes at low temperature. 相似文献

Single crystals of [Zn(NH3)4]3[Mo4Te4(CN)12] (I) and [Cd(NH3)4]3[W4Te4(CN)12] (II) were obtained by applying solutions of K7[Mo4Te4(CN)12] · 11H2O and K6[W4Te4(CN)12] · 5H2O in aqueous ammonia over solutions of ZnCl2 and Cd(NO3)2 in glycerol and were characterized by X-ray diffraction analysis. The IR spectra and thermal properties of compounds I and II were examined. 相似文献

Tetrakis(triphenylphosphoraneiminato)titanium, [Ti(NPPh3)4] The title compound has been prepared by the reaction of [TiCl2(NPPh3)2] with methyllithium and cyclopentadienyllithium, respectively, in hexane solution. [Ti(NPPh3)4] · 3 C7H8 crystallizes from toluene solution to form colourless, only slightly moisture sensitive crystals which were characterized by a crystal structure determination. Space group I41/a, Z = 8, lattice dimensions at ?80°C: a = b = 2160.7(2), c = 3334.2(3) pm, merohedral (110) twin, R = 0.077. The compound forms monomeric molecules with tetrahedrally coordinate titanium atoms and bonding parameters of TiN = 187.3 pm, PN = 155.1 pm, TiNP 150.4° in average. 相似文献

Synthesis and Properties of Tetrakis(Perfluoroalkyl)Tellurium Te(Rf)4 (Rf = CF3, C2F5, C3F7, C4F9) Te(CF3)4 is obtained from the reaction of Te(CF3)Cl2 with Cd(CF3)2 complexes as a complex with e. g. CH3CN, DMF. It is a light and temperature sensitive hydrolysable liquid. The reaction with fluorides yields the complex anion [Te(CF3)4F]−, with fluoride ion acceptors the complex cation [Te(CF3)3]+. With traces of water an acidic solution is formed. Te(CF3)4 acts as a trifluoromethylation reagent. The reaction with XeF2 gives hints for the formation of Ye(CF3)4F2. Properties and NMR spectra are discussed. The much more stable complexes of Te(Rf)4 (Rf = C2F5, C3F7, C4F9) are formed from the reaction of TeCl4 with the corresponding Cd(Rf)2 complexes. 相似文献

Syntheses and Characterizations of the First Tris and Tetrakis(trifluoromethyl) Palladates(II) and Platinates(II), [M(CF3)3(PPh3)]— and [M(CF3)4]2— (M = Pd, Pt) Tris(trifluoromethyl)(triphenylphosphino)palladate(II) and platinate(II), [M(CF3)3PPh3]—, and the tetrakis(trifluoromethyl)metallates, [M(CF3)4]2— (M = Pd, Pt), are prepared from the reactions of [MCl2(PPh3)2] and Me3SiCF3 / [Me4N]F or [I(CF3)2]— salts in good yields. [Me4N][M(CF3)3(PPh3)] crystallize isotypically in the orthorhombic space group Pnma (no. 62) with Z = 4. The NMR spectra of the new compounds are described. 相似文献

Solvent molecules have a great influence on the structure and stability of tellurium tetracyanide; whereas Te(CN)4 x (diglyme)(2) contains monomeric Te(CN)4 units, [Te(CN)3(micro-CN) x diglyme](n) is a coordination polymer. 相似文献

The reactions of appropriate ratios of K2TeO3 and [Mn2(CO)10)] in superheated methanol solutions lead to a series of novel cluster anions [Te4Mn3(CO)10] (1), [Te2Mn3(CO)9]2- (2), [Te2Mn3(CO)9]- (3), and [Te2Mn4(CO)12]2- (4). When cluster 1 is treated with [Mn2(CO)10]/KOH in methanol, paramagnetic cluster 2 is formed in moderate yield. Cluster 2 is oxidized by [Cu(MeCN)4]BF4 to give the closo-cluster [Te2Mn3(CO)9]- (3), while treatment of 2 with [Mn2(CO)10]/KOH affords the closo-cluster 4. IR spectroscopy showed that cluster 1 reacted with [Mn2(CO)10] to give cluster 4 via cluster 2. Clusters 1-4 were structurally characterized by spectroscopic methods or/and X-ray analyses. The core structure of 1 can be described as two [Mn(CO)3] groups doubly bridged by two Te2 fragments in a mu2-eta2 fashion. Both [Mn(CO)3] groups are further coordinated to one [Mn(CO)4] moiety. Cluster 2 is a 49 e- species with a square-pyramidal core geometry. While cluster 3 displays a trigonal-bipyramidal metal core, cluster 4 possesses an octahedral core geometry. 相似文献

Reactions of ClS[OCH(CF3)2]3 and S[OCH(CF3)2]2 with Phosphorus(III) Derivatives The sulfurane ClS[OCH(CF3)2]3 reacts with Me3P to give the phosphonium salt [Me3POCH(CF3)2]+Cl?, in the case of (MeO)3P products of an Arbuzov reaction are found: (MeO)2P-(:O)OCH(CF3)2 and MeCl; the sulfurane is reduced to the sulfoxylate S[OCH(CF3)2]2. The cyclic phosphite FP[OC(CF3)2C(CF3)2O] and P[OCH(CF3)2]3 furnish derivatives of pentacoordinated phosphorus upon reaction with ClS[OCH(CF3)2]3. The sulfoxylate S[OCH(CF3)2]2 oxidises Me3P, (MeO)3P and P[OCH(CF3)2]3 to form R3P? O and R3P? S (R = Me, OMe, OCH(CF3)2). The ether (CF3)2CHOCH(CF3)2 is isolated, too. 相似文献
