This paper deals with the synthesis of rhodium(I) Vaska-type complexes of the general form trans- [Rh(CO)X(PX3)] (X = halide, X aryl or alkyl substituent) when incorporating tertiary phosphine ligands and illustrates their simple application as probes to evaluate steric and electronic effects, specifically in tertiary phosphine ligands, analogous to the Tolman model. They are easy to prepare and do not exhibit the toxicity as the corresponding nickel complexes, while structural and infrared data can be conveniently utilised to estimate ligand properties with relative ease. These Vaska-type complexes are often obtained as by-products when reacting [Rh(mu-Cl)(CO)2] 2 with bidentate ligands in non-stoichiometric amounts, thus yielding unreacted dimer, which, upon addition of the tertiary phosphine, quantitatively converts to the Vaska-type complex. A representative summary of rhodium(I) Vaska-type systems is reported and structures correlated with steric and electronic properties of related literature complexes. Selected aspects of reactions of the corresponding arsine and stibine analogues are illustrated and solvent effects on equilibrium behaviour as well as the iodomethane oxidative addition described.

An alternating copolymer comprising 3,6-linked-9-(2-ethylhexyl)-9H-carbazole and 2,7-linked-3,6-dimethyl-9-(2-hexyldecy)-9H-carbazole has been prepared using Suzuki cross-coupling conditions. The polymer was characterised by nuclear magnetic resonance spectroscopy, UV-Vis absorption spectroscopy, fluorescence spectroscopy and its weight-average molecular weight was estimated using gel permeation chromatography. The polymer is thermally stable up to 420 C and displays a wide band gap (3.2 eV) and a narrow emission band at 400 nm with a full width at half maximum of 56 nm. Electroluminescence studies indicated that the polymer emitted principally blue light when blended with 2-(4-biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole and was found to be a good energy transfer donor to bis(2-(2?-benzothienyl)-pyridinato-N,C3?)iridium (acetylacetonate) and provided devices with an efficiency of 0.1 cd/A, and a turn-on voltage of 5.6 V.

A series of iron dinitrosyl complexes of the form Fe(NO) 2(P(C6H4X)3)2 (X = p-OMe (1), p-Me (2), m-Me (3), p-H (4), p-F (5), p-Cl (6), p-CF3 (7)) has been prepared from the reactions of Fe(NO)2(CO)2 and the respective triarylphosphines. Complexes 1-7 have been characterized by IR and 31P NMR spectroscopy, and by X-ray crystallography for 1 and 7. In general, the compounds with the more basic phosphines display lower upsilonNO stretches in the IR spectra than those with the less basic phosphines, and the trends in upsilonNO as a function of Hammett parameter and solvent donor/acceptor number were analyzed. The redox behavior of compounds 1-7 in CH2Cl2 were studied by cyclic voltammetry at a Pt electrode. In general, the compounds undergo one-electron oxidations. Infrared spectroelectrochemistry revealed that the oxidations generate the derivatives with upsilonNOs that are ?100 cm -1 higher in energy indicative of Fe(NO)2-centered oxidations.

Electroreduction of triphenylphosphine oxide to triphenylphosphine in an acetonitrile solution of tetrabutylammonium bromide in the presence of chlorotrimethylsilane was performed successfully in an undivided cell fitted with a zinc anode and a platinum cathode under constant current. A plausible mechanism involving, (1) one-electron reduction of triphenylphosphine oxide generating the corresponding anion radical [Ph3P-O-], (2) subsequent reaction with chlorotrimethylsilane affording the (trimethylsiloxy)triphenylphosphorus radical [Ph3P-OSiMe 3], and (3) further one-electron reduction followed by P-O bond fission leading to triphenylphosphine is proposed. In a similar manner, electroreduction of some triarylphosphine oxides and alkyldiarylphosphine oxides was executed to give the corresponding phosphine derivatives in good to moderate yields.
