The (COCl)2/Hantzsch ester is found to be an effective system for the metal-free reduction of tertiary phosphine oxides. The reaction proceeds under mild conditions, and is applicable to triarylphosphine oxides and alkyldiarylphosphine oxides to produce the corresponding tertiary phosphines in g...
The reaction of [RhCl(CO)2]2 with tricyclohexylphosphine oxide (Cy3PO) (Rh/Cy3PO molar ratio 1) gives the dicarbonyl derivative, cis-[RhCl(CO)2(Cy3PO)], which is stable toward loss of carbon monoxide and subsequent dimerization. An X-ray structure determination shows that the rhodium is in a squ...
Most high and medium oxidation state (O.S. ≥ 3) metal and non-metal fluorides and oxide fluorides have Lewis acidic properties, although detailed exploration of their chemistry with neutral ligands, which differs significantly from that with chloride, bromide or iodide co-ligands, has only been...
A simple copper-catalyzed direct difunctionalization of alkenes with H-phosphine oxides and dioxygen for the synthesis of β-ketophosphine oxides has been developed under mild conditions. The present protocol, which utilizes an inexpensive catalyst, readily available materials, and environmental...
The products of the reactions of tricyclohexylphosphine oxide, Cy3PO = L, with lanthanide chlorides (Ln = La, Dy, Er, Yb) have been investigated by solution NMR spectroscopy and single crystal X-ray crystallography (Dy, Er). The structures of the complexes are based on a pentagonal bipyramidal a...

The monoreduction of trifluoromethanesulfonyl chloride by an appropriate phosphine, preferentially tricyclohexylphosphine, generates the reactive trifluoromethanesulfinyl chloride CF3SOCl as donor of CF3S(O)+ cation. The direct trifluoromethylsulfinylation of indoles, pyrroles, other azaarenes, ...
This is a first report on the use of the bis(tricyclohexylphosphine)nickel (II) dichloride complex (abbreviated as NiPCy3) into MgH2 based hydrogen storage systems. Different composites were prepared by planetary ball-milling by doping MgH2 with (i) free tricyclohexylphosphine (PCy3) without or ...
Complexes of lanthanide bromides with tricyclohexylphosphine oxide (Cy3PO) form three distinct structural classes. Type I complexes LnBr3(Cy3PO)3 have been structurally characterised for Ln = La, Pr, Nd, Gd and Ho and are molecular 6 coordinate with a distorted meridional octahedral arrangement....
Dense poly(4-vinyl pyridine) (P4VP) brushes were grafted on the surface of silica nanoparticles (SiO2-NP) via surface-initiated atom transfer radical polymerization (ATRP). The “grafting from” method was discussed and the morphology, composition and structure of the P4VP-grafted SiO2 were char...
