DOI: 10.1021/acs.organomet.1c00241
Abstract: The synthesis and characterization of nickel, cobalt, and iron complexes of the bis(phosphine)carbodicarbene (CDC) ligand 1 is described. The square-planar complexes can be synthesized without the isolation of the deprotonated carbodicarbene ligand, and three different synthetic methods… read more here.

DOI: 10.1021/jacs.0c13236
Abstract: A novel catalytic system based on copper(I) and chiral bis(phosphine) dioxides is described. This allows the arylation of silyl enol ethers to access enolizable α-arylated ketones in good yields and enantiomeric excess up to 95%.… read more here.

DOI: 10.1039/d2ra04684a
Abstract: A series of neutral luminescent bis(phosphine) Cu(i) complexes of pyridyl-tetrazolate ligands (L1–L3) with the general formula [CuI(Ln)(P^P)] (1–6) were synthesized, which have been well characterized by IR, UV/vis, CV, 1H NMR and 31P NMR. For… read more here.
