The carbonyl cobalt complex Cp*Co(CO)I2 catalyzes carbenoid Co alkylation of N-(pyrimidin-2-yl)indole with methyl 3,3,3-trifluoro-2-diazopropionate regioselectively giving 2-substituted indole, while the N,N’-ligated cations [CpCo(L)I]+ (L = bipy, phen) provide 3-substitution exclusively. The structure of [CpCo(phen)I]PF6 was investigated by X-ray diffraction.
Reaction of a trinuclear silver pyrazolate {[3,5-(CF3)2Pz]Ag}3 complex with tricyclohexylphosphine at different reagent ratios leads to the formation of heteroleptic dinuclear or tetranuclear complexes. According to the single crystal X-ray analysis of the dinuclear complex, hexane molecules are incorporated into the cavities formed as the result of supramolecular packing. Coordination of a phosphine ligand makes dinuclear silver pyrazolate to exhibit blue emission at room temperature. 相似文献
