The reaction of 1-alkynes with acyl azides in the presence of [Tpm *,BrCu(NCMe)]BF4 [Tpm*,Br = tris(3,5-dimethyl-4-bromopyrazolyl)methane] as the catalyst provides 2,5-oxazoles in moderate to high yields. This is a novel transformation of the CuAAC type that constitutes a significant variation of the commonly observed [3 + 2] cycloaddition...

Five chiral iron-containing ionic liquids were synthetized from several chiral ionic liquids (CILs) based on different imidazolium cations. These novel compounds were prepared through an easy synthetic method involving mixing 1 equivalent of iron salt FeX3 (X = Cl or Br) and 1 equivalent of chiral ionic liquid. The soobtained chiral iron-based...

Ligand control of metal nanoparticles (MNPs) is rapidly gaining importance as ligands can stabilize the MNPs and regulate their catalytic properties. Herein we report the first example of Pt NPs ligated by imidazoliumamidinate ligands that bind strongly through the amidinate anion to the platinum surface atoms. The binding was established by...
