The dimer [Ir(CO)2I(µ-I)Me]2 2 reacts with CO to give the tricarbonyl [Ir(CO)3I2Me] 3 identified by high pressure IR and NMR spectroscopy and isotopic labelling; kinetic data for the migratory CO insertion reaction of 3 support its role as a key intermediate in iridium catalysed methanol carbonylation.

The iridium/iodide-catalyzed carbonylation of methanol to acetic acid is promoted by carbonyl complexes of W, Re, Ru, and Os and simple iodides of Zn, Cd, Hg, Ga, and In. Iodide salts (LiI and Bu(4)NI) are catalyst poisons. In situ IR spectroscopy shows that the catalyst resting state (at H(2)O levels > or = 5% w/w) is fac,cis-[Ir(CO)(2)I(3)Me](-), 2. The stoichiometric carbonylation of 2 into [Ir(CO)(2)I(3)(COMe)](-), 6, is accelerated by substoichiometric amounts of neutral promoter species (e.g., [Ru( ...

Abstract Kinetic measurements are reported for the oxidative addition reactions of methyl chloride and acetyl chloride with [Ir(CO) 2 Cl 2 ] − . At 40°C the second‐order rate constant for MeCOCl addition is estimated to be nearly 40 000 times larger than that for MeCl addition. The Ir(III) products, [Ir(CO) 2 Cl 3 R] − (R = Me, COMe) have been isolated and characterised by spectroscopy and x‐ray crystallography. In the absence of excess organic chloride, both Ir(III) complexes undergo reductive elimination of ...

New homogeneous catalysts for the hydration of nitriles to amides are described. The catalyst precursors are coordination compounds of Pt(II) with secondary phosphine oxides. They contain a hydrogen bridged mono-anionic didentate phosphinito group, together with a third phosphine oxide ligand and a monodentate anionic ligand, either hydride or chloride. Reacting the chloride with silver ion, or the hydride with water gives a cationic species which is the active catalyst. On coordination to the cation ...

The reaction of Pd(dppp)(OAc)2 [dppp = 1,3-bis(diphenylphosphino)propane] with B(C6F5)3 in situ gives an efficient catalyst for alkene/CO polymerization in aprotic media. The borane is consumed during the polymerization, and its fluoroaryl groups are incorporated into the polymer chain ends. In the absence of the monomers the catalyst components react to give palladium(II)−pentafluoroaryl complexes formulated as Pd(dppp)(C6F5){[B(C6F5)3]yOH} (y = 1, 3a; y = 2, 3b). Complex 3a can be isolated, albeit as ...

Those with disabilities who have lost their legs must use a prosthesis to walk. However, traditional prostheses have the disadvantage of being unable to move and support the human gait because there are no mechanisms or algorithms to control them. This makes it difficult for the wearer to walk. To overcome this problem, we developed an insole device with a wearable sensor for real-time gait phase detection based on the kNN (k-nearest neighbor) algorithm for prosthetic control. The kNN algorithm is ...

The present research discusses structural reforms in the regulation of public bus services in Israel. In 2000, the market underwent a significant change; as a result, some of the bus services on fixed routes that were previously provided by two monopolistic operators are currently provided by means of competitive tendering. The research examined the reasons for this change, the measures taken in order to implement it, and the outcomes from the perspective of time. The findings indicated that, as ...

Measuring these spatially varying strains is difficult but of prime importance for understanding the effects on carrier mobility, non-radiative recombination, degradation, and other optoelectronic properties. Local strain can be mapped using the shifts in vibrational frequencies using Raman or infrared microscopy. ...

The structure of the ring insertion product 1b obtained from the reaction of [Pt(dppm)(CH2Cl2] (dppm = Ph2PCH2PPh2) with triphenylphosphine has been confirmed by X-ray crystallography of the hexafluorophosphate salt. The bis-chelate complex (IIIa) has been isolated from the reaction of [Pt(dppm)(CH2Cl2] (II) with diphenylphosphine in dichloromethane. Iodination of Ib leads to selective cleavage of the chloromethyl group, and subsequent iodide abstraction with silver ion gives a solvated cation (V). The ...
