abstract = {The selenoether-functionalized imidazolium salt
N-[(phenylseleno)methylene)]-N′-methylimidazolium chloride
(LH+Cl–) was transformed into the metal–carbene
complexes [AgCl(L)], [AuCl(L)], [PdCl2(L)], and [PtCl2(L)]
by the reaction with Ag2O and an additional transmetalation
reaction of [AgCl(L)] with [(THT)AuCl], [(COD)PdCl2], and
[(COD)PtCl2], respectively (THT = tetrahydrothiophene, COD =
cyclooctadiene). The compound [AuI2Cl(L)] was prepared by
oxidation of [AuCl(L)] with elemental iodine. The
microwave-assisted decomposition of [PdCl2(L)] in the ionic
liquid 1-butyl-3-methylimidazolium
bis(trifluoromethylsulfonyl)imide ([BMIm]NTf2) or in
propylene carbonate led to the formation of Pd17Se15
nanoparticles of 51 ± 17 or 26 ± 7 nm diameter,
respectively. The decomposition of the platinum complex
resulted in either small Pt clusters around 1 nm size from
the ionic liquid suspension or Pt nanoparticles of 3 ± 1 nm
diameter in propylene carbonate. High-resolution X-ray
photoelectron spectroscopy (HR-XPS) and 13C
cross-polarization magic-angle spinning (CP MAS) NMR
indicated that the surface of Pt clusters and crystalline Pt
nanoparticles is formed by an amorphous Pt(II)/Se shell and
by carbene ligand residues.},
