New radical metalloids, NN-AuSIMes and NNCu( bdmpphen), were prepared and their properties were investigated. They were applied to Pd(0)-mediated crosscoupling reactions with aryl halides (ArX) to produce 2-aryl (nitronyl nitroxide) s in moderate to high

A cross-coupling reaction using nitronyl nitroxide (NN) as a coupling partner was developed: Refluxing a mixture of [AuI(NN-2-ido)(PPh3)] and aryl iodide (ArI) in THF in the presence of 10 mol% [Pd(PPh3)4] produced a cross-coupling product NN-Ar in a high yield. This method allowed the direct introduction of the NN radical onto various poly- and heterocyclic aromatic rings.
SUBSTITUENT EFFECT ON THE REACTION OF 2-(SUBSTITUTED PHENYL)-4,5-DIHYDRO-4,4,5,5-TETRAMETHYLIMIDAZOL-1-OXYL 3-OXIDES WITH NITRIC OXIDE: AN EXPERIMENTAL AND MNDO STUDY

The relative rate constants of the oxygen transfer reaction of 2-(substituted phenyl)-4,5-dihydro-4,4,5,5-tetramethylimidazol-1-oxyl 3-oxides with nitric acid have been measured by using liquid chromatography (h.p.l.c.).The Hammett ρ value (-0.37) indicates that electron-donating substituents favour the reaction.This can be explained by a mechanism which includes electron transfer to nitric oxide and can be rationalised by frontier orbital energies and electron densities on the nitroxyl oxygen calculated by semiempirical MNDO methods.
