Abstract

By cross-coupling of 2-iodo-polyfluoroanilines with a [AuPPh3NN] complex (where NN is 4,4,5,5- tetramethyl-3-oxide-1-oxyl-2-imidazolin-2-ide) in the presence of [Pd(PPh3)4], nitroxide radicals (2-aminopolyfluorophenyl- 4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazol-3-oxide-1-oxyls) are synthesized. Their molecular and crystal structures are determined by the X-ray crystallographic analysis. It is shown that in the solid phase there are both intra- and intermolecular hydrogen bonds between NH2 groups and O atoms of paramagnetic fragments, which link the molecules into chains or dimers.
