Journal ArticleDOI
Recent progress in the generation and use of nitrogen-centred radicals.
TL;DR: This tutorial review will help increase the awareness of synthetic chemists and help revive the interest in these forgotten species of nitrogen-centred radicals.
Journal ArticleDOI
On the trail of xanthates: some new chemistry from an old functional group
Samir Z. Zard,Samir Z. Zard +1 more
TL;DR: The use of free radical reactions in organic synthesis has witnessed an extraordinary development in recent years as discussed by the authors, and the number of synthetically useful radical-generating systems is still limited, and most applications have relied on tin hydride chemistry.
Journal ArticleDOI
A useful synthesis of pyrroles from nitroolefins
Derek H. R. Barton,Derek H. R. Barton,J. Kervagoret,J. Kervagoret,Samir Z. Zard,Samir Z. Zard +5 more
TL;DR: In this article, it was shown that β-acetoxy-nitro compounds react with α-isocyano-esters in the presence of an organic base to give pyrroles in good yield.
Journal ArticleDOI
Dithiocarbamates as universal reversible addition-fragmentation chain transfer agents
TL;DR: The key parameter for the control with N,N-disubstituted (A) or cyclic (B) dithiocarbamates was found to be the conjugation of the lone pair of electrons of the nitrogen atom with carbonyl or aromatic groups.

Method for block polymer synthesis by controlled radical polymerisation
TL;DR: In this paper, a method for polymerizing block polymers of general formula (I) which consists in contacting an ethylenically unsaturated monomer of formula: CYY'(=CW-CW')a=CH2 is described.
