AbstractA mixture of sodium nitrite and ascorbic acid is able to control the radical polymerization of tert-butyl methacrylate (tBMA) in water at 80°C. Indeed, sodium nitrite is reduced by the ascorbic acid, and the nitric oxide (NO) which is formed insitu is nothing but a promoter of nitroxyl radicals. The radical polymerization of tBMA is thus basically controlled by a nitroxide-mediated process.

Synthetic Methodologies

Synthetic methodologies involving the formation of carbon-carbon bonds from carbon-hydrogen bonds are of significant synthetic interest, both for efficiency in terms of atom economy and for their undeniable usefulness in late-stage functionalization approaches. Combining these aspects with being metal-free, the radical C-H intermolecular arylation procedures covered by this review represent a powerful green means for the synthesis of (hetero)biaryl systems. 1.
