[{Cu(IPr)}2(μ-OH)][BF4]: synthesis and halide-free CuAAC catalysis.
نویسندگان
چکیده
The preparation under protic conditions of the first μ-hydroxo dicopper(I)-NHC complex is reported. Its application as a CuAAC catalyst was investigated, evidencing a remarkable enhancement of catalytic efficiency in the presence of 4,7-dichloro-1,10-phenanthroline and highlighting the beneficial effect of the absence of coordinating halides.

Trapping atmospheric CO2 with gold.
The ability of gold-hydroxides to fix CO2 is reported. [Au(IPr)(OH)] and [{Au(IPr)}2(μ-OH)][BF4] react with atmospheric CO2 to form the trigold carbonate complex [{Au(IPr)}3(μ(3)-CO3)][BF4]. Reactivity studies revealed that this complex behaves as two basic and one cationic Au centres, and that it is catalytically active. DFT calculations and kinetic experiments have been carried out.

متن کاملNew method for preparation of MWCNT-SO3H as an efficient and reusable catalyst for the solvent-free synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones
Multiwalled carbon nanotubes (MWCNTs) have been functionalized with -SO3H groups using new three steps chemical routes. Firstly, OH groups have been attached to CNT surfaces through a radical reaction. The second step involves converting the hydroxyl groups into the oxide one and last step included the attachment of –SO3H groups on the MWCNTs surfaces in the presence of 1-butyl-3-methyl imidazo...
