The cationic triple-decker complexes [CpCo(1,3-C3B2Me5)M(C5R5)]+ (M = Rh (2), Ir (3), R = H (a), Me (b)) with the bridging diborolyl ligand were synthesized by the reaction of the sandwich anion [CpCo(1,3-C3B2Me5)]- (1) with the halide complexes [CpMI2]2 or [Cp*MCl2]2 (Cp* = C5Me5). The structures of [2b]PF6 and [3b]PF6 were established by X-ray diffraction. The nature of the metal—diborolyl bond in these complexes was analyzed using the energy
decomposition scheme. 相似文献

Cationic triple-decker complexes [CpCo(1,3-C3B2Me5)Ru(arene)]PF6 (arene is benzene (2a), p-cymene (2b)) with a bridging diborolyl ligand were synthesized by the reaction of the sand-wich anion [CpCo(1,3-C3B2Me5)]− (1) with [(arene)RuCl2]2. The structure of [2b]PF6 was confirmed by X-ray diffraction analysis. 相似文献

A number of new phenylated polyfluorenes with blue emission are synthesized via the Diels-Alder reaction in chloronaphthalene and supercritical carbon dioxide. It is shown that these polymers are thermally stable. A comparative analysis of their properties shows that a ??green?? solvent is a suitable alternative to organic solvents for obtaining phenyl-substituted polyfluorenes via the Diels-Alder reaction. 相似文献

The synthesis of new P*-mono- and P*,N-bidentate diamidophosphites, containing 1,3,2-diazaphospholidine rings formed starting from (2S,3S)-N 2,3-dimethyl-N 1-phenylpentane-1,2-diamine, is described. Comparison of their efficiency in the Pd-catalyzed enantioselective allylation with (E)-1,3-diphenylallyl acetate showed that up to 97% ee was reached in the reaction involving dimethyl malonate as a C-nucleophile. The Pd-catalyzed desymmetrization of N,N′-ditosyl-meso-cyclopent-4-ene-1,3-diol biscarbamate gave up to 61% ee. 相似文献

The demethylation of the cations [Cp*M(??-9-SMe2-7,8-C2B9H10)]+ (1a,b) with PhCH2SNa affords neutral metallacarboranes Cp*M(??-9-SMe-7,8-C2B9H10) (2a: M = Rh; 2b: M = Ir). The reverse reaction can be performed by the treatment of complexes 2a,b with MeI in the presence of TlPF6. The structures of complexes 2a,b were determined by X-ray diffraction. 相似文献

Cationic complexes [(diene)Co(??-C6Me6)]+ (diene is buta-1,3-diene (2a), 5-isopropyl-2-methylcyclohexa-1,3-diene (2b), cycloocta-1,3-diene (2c), and cyclohexa-1,5-diene (2d)) were synthesized by the reaction of [Co(??-C6Me6)2]+ (1) with dienes in a CH2Cl2-Me2CO mixture. In the absence of dienes, cation 1 undergoes hydrogenation to form [(1,2,3,4,5,6-HMCD-1,3)-Co(??-C6Me6)]+ (HMCD is hexamethylcyclohexadiene, 2e). Structures [2c?Ce]PF6 were determined by X-ray diffraction analysis. According to the DFT calculations, the Co-C6H6 bond in the complexes with conjugated dienes is stronger than that in the complexes with nonconjugated dienes. 相似文献

Decahydro-closo-decaborate anion, [B10H10]2–, undergoes regioselective deuterio-exchange in methanol-d4. Selectively deuterated derivatives [1,10-B10H8D2]2– and [2,3,4,5,6,7,8,9-B10H2D8]2– were synthesized. 相似文献
