Radicals in Transition Metal Catalyzed Reactions? Transition Metal Catalyzed Radical Reactions? – A Fruitful Interplay Anyway

Ullrich Jahn
- 01 Jan 2011 - 
TL;DR: This review summarizes the current status of radical-based transition metal catalyzed reactions in organic chemistry and covers catalytic radical reactions involving group 4 to group 7 elements.
Journal ArticleDOI

Very strong organosuperbases formed by combining imidazole and guanidine bases: synthesis, structure, and basicity.

Katarina Vazdar, +5 more
- 27 Jan 2014 - 
TL;DR: The synthesis of N,N'-bis(imidazolyl)guanidine bases (BIG bases) is reported, probably the strongest known phosphorous-free organic bases both in solution and in the gas phase.
Journal ArticleDOI

Acceptor-substituted ferrocenium salts as strong, single-electron oxidants: synthesis, electrochemistry, theoretical investigations, and initial synthetic application.

Dushant Khobragade, +5 more
- 24 Sep 2012 - 
TL;DR: An initial application of selected derivatives in an oxidative bicyclization revealed that they mediate the transformation under considerably milder conditions than ferrocenium hexafluorophosphate.
Journal ArticleDOI

General and Efficient α‐Oxygenation of Carbonyl Compounds by TEMPO Induced by Single‐Electron‐Transfer Oxidation of Their Enolates

Emanuela Dinca, +5 more
- 01 Aug 2012 - 
TL;DR: In this paper, a method for the synthesis of protected α-oxygenated carbonyl compounds is reported, which is based on the single-electron-transfer oxidation of easily generated enolates to the corresponding α-carbonyl radicals.
Journal ArticleDOI

Evolution of moth sex pheromone composition by a single amino acid substitution in a fatty acid desaturase

Aleš Buček, +7 more
- 13 Oct 2015 - 
TL;DR: It is demonstrated that gene duplication and a single amino acid substitution in fatty acid desaturase (FAD) catalyzing production of diunsaturated moth pheromone precursors is sufficient for acquisition of 3UFA SP component precursORS.
