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
Nitronyl nitroxide as a coupling partner: Pd-mediated cross-coupling of (nitronyl nitroxide-2-ido)(triphenylphosphine)gold(i) with aryl halides

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.

The synthesis of biphenyls substituted with nitronyl-nitroxide organic radicals is described. To investigate the Suzuki-type cross-coupling reaction conditions in the presence of the radical, a model compound 1 was prepared. The successful coupling was extended to cyano-functionalized, biphenylic, paramagnetic molecules. Both the ortho- and meta-iodophenyl-nitronyl-nitroxide radicals were used to synthesize radicals 2 and 3. The characterizations of the spin-labelled molecules obtained by this synthetic strategy include two X-ray crystal structures and magnetic measurements. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
