A cyclometalated iridium(III) complexcontaining a N∧C∧N-coordinating terdentate ligand [Ir(dpyx-N,C,N)Cl(μ-Cl)]2 was found to be a general and highly effective catalyst for the α-alkylation of ketones and N-alkylation of amines with alcohols. In the presence of catalyst (1 mol % Ir) and base (0.2–0.5 equiv), a variety of desirable products were obtained in good yields under an air atmosphere. Notably

Continuous reductiveamination of aldehydes with nitroarenes over a Pd–Pt–Fe3O4 catalyst was performed. We used NH3BH3 as not only a hydrogen source for nitro reduction, but also a reductant for imine reduction. Secondary aromatic amines were obtained in the continuous flow reaction in good to excellent yields.
在Pd–Pt–Fe 3 O 4催化剂上用硝基芳烃进行醛的连续还原胺化。我们不仅将NH 3 BH 3用作硝基还原的氢源,还将其用作亚胺还原的还原剂。在连续流动反应中以良好至优异的产率获得了仲芳族胺。

Compounds of formula (1), pharmaceutically acceptable salts, solvates and in vivo hydrolysable esters thereof, have activity as pharmaceuticals, in particular as modulators of chemokine receptor (especially CXCR2) activity, and may be in the treatment (therapeutic or prophylactic) of conditions/diseases in human and non-human animals which are exacerbated or caused by excessive or unregulated production of chemokines.
