Significance

A Suzuki-Miyaura cross-coupling reaction between aryl boronic acids with an aryl iodide bearing a nitronyl-nitroxide radical is reported. The modest to good yields are assumed to be due to the instability of the nitronyl-nitroxide biaryl products, suggesting potential improvement by selection of more suitable catalysts. The products were characterized by SQUID (superconducting quantum interference device), a method that confirms identity and purity; two of them were fully characterized by X-ray crystal structure analysis.
