Tetrakis(triphenylphosphine)palladium(0) was first prepared by Lamberto Malatesta et al. in the 1950s by reduction of sodium chloropalladate with hydrazine in the presence of the phosphine. [4] It is commercially available, but can be prepared in two steps from Pd(II) precursors: PdCl 2 + 2 PPh 3 → PdCl 2 (PPh 3) 2
Portopulmonary hypertension (PPH) [1] is defined by the coexistence of portal and pulmonary hypertension. PPH is a serious complication of liver disease, present in 0.25 to 4% of all patients with cirrhosis. Once an absolute contraindication to liver transplantation, it is no longer, thanks to rapid advances in the treatment of this condition. [2]
(Triphenylphosphine)iron tetracarbonyl is a coordination complex with the formula Fe(CO) 4 (PPh 3) (Ph = C 6 H 5). An off-white solid, this complex is derived from iron pentacarbonyl by replacement of one carbonyl ligand by triphenylphosphine (PPh 3).
PPh 3 can also form an adduct with Te, although this adduct primarily exists as (Ph 3 P) 2 Te rather than PPh 3 Te. [9] Aryl azides react with PPh 3 to give phosphanimines, analogues of OPPh 3, via the Staudinger reaction. Illustrative is the preparation of triphenylphosphine phenylimide: PPh 3 + PhN 3 → PhNPPh 3 + N 2. The phosphanimine can ...
