Cycloaurated triphenylphosphine-sulfide and -selenide.
The first examples of cycloaurated phosphine sulfides and triphenylphosphine selenide have been synthesised; these complexes are fairly rare examples of gold(iii) complexes with potentially reducing sulfur- and selenium-donor ligands. The cycloaurated complex (AuCl(2)(2-C(6)H(4)P(S)Ph(2)) was synthesised in good yield by transmetallation of the organomercury precursor Hg(2-C(6)H(4)P(S)Ph(2))(2)...

been investigated using polarography, cyclic voltammetry, coulometry, a n d product analysis. TPP proceeds by a one-electron transfer to form the anion radical which undergoes cleavage of a phenyl group. The electrochemical reduction of triphenylphosphine (TPP) and triphenylphosphine oxide (TPPO) has The reduction of everal recent papers have been concerned with the S polarography of triphenylp...
متن کاملUtility of Triphenylphosphine Dihalides in Organic Reactions : Esterification Using Triphenylphosphine Dibromide as the Dehydrating Agent
A new esterification method was investigated using triphenylphosphz'ne dibromide as a dehydrating agent. This investigation has established that the method is useful when the acid is aromati~ or arylallylic. That primary and secondary alcohols esteTZfy acid satisfactorily whereas tertiary alcohols fail to react was also established in this experiment.
متن کاملBis(triphenylphosphine)iminium bromide acetonitrile monosolvate
The title compound, C(36)H(30)NP(2) (+)·Br(-)·C(2)H(3)N, crystallized from a CH(3)CN/OEt(2) solution as an acetonitrile solvate. The central P-N-P angle [142.88 (10)°] is significantly larger than in the corresponding chloride and iodide structures.
متن کاملComplexes of triphenylphosphine oxide with lanthanide bromides
The reaction between hydrated lanthanide bromides and triphenylphosphine oxide in 1:3 and 1:4 ratios in ethanol gave a series of complexes [LnBr2(Ph3PO)4]Br (Ln = Pr, Nd, Gd, Tb, Er, Yb, Lu) which contain ethanol and water in the lattice, regardless of the ratio of reactants used. The single crystal x-ray structures of [NdBr2(Ph3PO)4]Br, [GdBr2(Ph3PO)4]Br and [YbBr2(Ph3PO)4]Br have been determi...
