Cabral, Bruno N.,Zawatski, Luana E.,Abram, Ulrich,Lang, Ernesto S.
, p. 739 - 743 (2015)
The reaction of sodium phenylselenolate and copper(I) chloride generates in situ a "CuSePh" species, which can be stabilized by N,N′-donor ligands such as bpy (2, 2′-bipyridine) or phen (1, 10-phenanthroline) in order to generate compounds with μ2/s

Five copper zinc phenylchalcogenolate complexes [(iPr3PCu)3(ZnMe2)2(SPh)3] (1), [(iPr3PCu)2(ZnPh)4(SPh)6] (2), [(iPr3PCu)2(ZnEt)4(SPh)6] (3), [(iPr3PCu)3(ZnEt)(SePh)4] (4), and [(iPr3PCu)3Cu(iPr3PZn)(TePh)6] (5) were synthesized by the reaction of phosphine stabilized copper phenylchalcogenolate complexes with ZnR2 (R = Me, Et, Ph) with and without additional chalcogenol. The novel mixed metal compounds were characterized by single-crystal X-ray structure analysis and NMR spectroscopy. 4 and 5 are the first examples of compounds with a Zn–Se–Cu or a Zn–Te–Cu linkage, respectively.

Herein, a copper free, selenated NHC-Pd(II) full pincer catalyzed Sonogashira cross coupling reaction of ferrocene/phenyl substituted β-chloro-cinnamaldehyde/acrylo-nitrilesmalononitrile has been established for the synthesis of novel ferrocenated enynes at feasible reaction condition. 0.002 mol % of the selenated NHC-Pd(II) pincer complex was found to be highly efficient to couple various substituted acetylenes with β-chloro-cinnamaldehyde/acrylonitriles/malononitrile in just 5 h under the areobic conditions. A library of 26 new ferrocene substituted enyne derivatives has been developed through the present Sonogashira reaction. Electrochemical response for some selective compounds was also investigated.
(η6-Benzene)Ru(II) half-sandwich complexes of pyrazolated chalcogenoethers for catalytic activation of aldehydes to amides transformation
Sharma, Kamal Nayan,Ali, Munsaf,Srivastava, Avinash Kumar,Joshi, Raj Kumar
, p. 69 - 77 (2018/11/10)
The reaction of [(η6-C6H6)RuCl(μ-Cl)]2 with chalcogenoether substituted 1H-pyrazole ligands (L1-L3) in methanol have yielded three novel Ru(II) half-sandwich complexes [(η6-C6H6)RuCl(L)]PF6 (1–3) in high yield under the ambient reaction conditions. The NMR, MS and FT-IR analytical techniques were used to identify their structures. The molecular structures of the complexes 2 and 3 were established with X-ray crystallographic analysis and revealed a pseudo-octahedral half sandwich piano-stool geometry around ruthenium in each complex. Complexes 1–3 are thermally robust and were found to be insensitive towards the air and moisture. All the complexes were found to be catalytically active and produced the excellent yields of amides (up to 95%) from corresponding aldehydes. In contrast to the previous reported catalytic systems for aldehyde to amide transformation, the present complexes 1–3 are very efficient and have several advantages in terms of low catalyst loading, reaction time, temperature and wide applicability for various substituted aldehydes. Owing to the stronger σ-donor coordination properties of selenium containing ligands, the complex 2 was found to be more efficient as compare to the sulphur and tellurium analogues.
