Nitric oxide reactions with activated

It is possible to replace one isocyanide by triphenylphosphine, or to replace two isocyanides with diphos, giving phosphine analogues of these complexes. These species are not available from analogous reactions of phosphine-palladium(O) and (II) complexes. Reactions with active alkyl halides proceeds with oxidation nitric oxide also oxidizes these complexes. [Eqs. (31, 32)]. 

The catalytic activity of ln/H-ZSM-5 for the selective reduction of nitric oxide (NO) with methane was improved by the addition of Pt and Ir which catalyzed NO oxidation, even in the presence of water vapor. It was also found that the precious metal, particularly Ir loaded in/H-ZSM-5 gave a low reaction order with respect to NO, and then showed a high catalytic activity for the reduction of NO at low concentrations, if compared with ln/H-ZSM-5. The latter effect of the precious metal is attributed to the enhancement of the chemisorption of NO and also to the increase in the amount of NO2 adsorbed on in sites.

Nitric Oxide. Rates of nitric oxide exchange with CoI(NO)2(PPh3) in toluene solution are much greater than for nitric oxide exchange with Co(CO)3(NO) or with Fe(CO)2(NO)a in the gas phase. The reaction in toluene is zero-order in nitric oxide concentration, but in the gas phase the reaction is first-order in nitric oxide. A fuller understanding of these rate and rate-law differences may develop when the preliminary report on the solution studies is amplified in the promised full version which will include activation parameters.
