Luminescent copper(I)-based compounds have recently attracted much attention since they can reach very high emission quantum yields. Interestingly, Cu(I) clusters can also be emissive, and the extension from small molecules to larger architecture could re
Catalyst- and solvent-free hydrophosphination and multicomponent hydrothiophosphination of alkenes and alkynes

The hydrophosphination of carbon-carbon multiple bonds has been generally performed under acid, base or metal catalysis in different solvents. Herein, alkyl and alkenyl tertiary phosphines are obtained by the addition of diphenylphosphine to alkenes and alkynes, respectively, in the absence of a solvent and a catalyst. In the presence of elemental sulfur, the corresponding alkyl and alkenyl tertiary phosphine sulfides are synthesized in a three-component process. These simple methods, which meet most of the principles of Green Chemistry, are highly regioselective towards the anti-Markovnikov products and diastereoselective towards the Z alkenyl phosphines. The mechanistic aspects of the reactions are also tackled and the efficiency of the latter is compared with that of the catalytic methods.

The hydrophosphanation of alkenes, an atom-economy process typically promoted by radicals or metal species, has been shown to take place in the absence of a catalyst, under solvent-free conditions and in a regioselective manner.

To develop functional systems based on the weak-link approach (WLA), it is important to understand how solvent and ligand binding strength alter the coordination geometry of complexes formed from this method. A series of phosphinoalkyl thioether (PS) hemi
t-BuOK-catalyzed addition phosphines to functionalized alkenes: A convenient synthesis of polyfunctional phosphine derivatives

The use of t-BuOK in DMSO allows a smooth addition of Ph2PH, Cy2PH and Ph2P(O)H to various functionalized alkenes leading to polyfunctional phosphines in good yields. This method has been used to prepare precursors for P,P- and P,N-ligands.
Cyanide complexes of nickel(II) with hybrid bidentate ligands containing phosphorus and nitrogen or sulfur donor atoms

Nickel cyanide complexes of the types [Ni(CN)2(ligand)2] and [Ni(CN)2(ligand)3] derived from the four hybrid bidentate ligands 1-(2′-pyridyl)-2-(diphenylphosphino)ethane, 1-(thiomethyl)-2-(diphenylphosphino)ethane, 1-(thioethyl)-2-(diphenylphosphino)ethane, and 1-(thiophenyl)-2-(diphenylphosphino)ethane are described. The complexes [Ni(CN)2(ligand)2] can be four- or five-coordinate. In the first case the bidentate ligands act as monodentate groups by bonding only through phosphorus donor atoms, whereas in the five-coordinate complexes both mono- and bidentate types of coordination of the ligands are involved. The complexes [Ni(CN)2(ligand)2] in solution can react with an excess of ligand to give five-coordinate species of the type [Ni(CN)2(ligand)3], in which only the phosphorus end of the ligand is bonded to the metal atom. The coordination number and stereochemistry of the complexes have been established on the basis of spectroscopic, conductivity, and molecular weight measurements. With the ligands containing phosphorus and sulfur, five-coordinate cationic complexes of formula [Ni(CN)(ligand)2]+ are also obtained, for which, on the basis of the visible spectra, a square-pyramidal structure is proposed.
