Journal ArticleDOI
Carbocations as Lewis Acid Catalysts: Reactivity and Scope
TL;DR: In this paper, the authors examined the strength of efficient metal-free catalysis and demonstrated efforts towards more sustainable processes through implementation of strategies that meet several of the 12 principles of Green Chemistry.
Journal ArticleDOI
Olefin Metathesis in Confined Geometries: A Biomimetic Approach toward Selective Macrocyclization.
Felix Ziegler,Johannes Teske,Iris Elser,Michael Dyballa,Wolfgang Frey,Hamzeh Kraus,Niels Hansen,Julia Rybka,Ulrich Tallarek,Michael R. Buchmeiser +9 more
TL;DR: A biomimetic approach that utilizes spatial confinement to increase macrocyclization selectivity in the ring clos-ing metathesis of various dienes at elevated substrate concentration up to 25 mM using an olefin me-tathesis catalyst selectively immobilized inside ordered mesoporous silicas with defined pore diameters is presented.
Journal ArticleDOI
Non-decarbonylative photochemical versus thermal activation of Bu4N[Fe(CO)3(NO)] – the Fe-catalyzed Cloke–Wilson rearrangement of vinyl and arylcyclopropanes
Che-Hung Lin,Dominik Pursley,Johannes E. M. N. Klein,Johannes Teske,Jennifer A. Allen,Fabian Rami,Andreas Köhn,Bernd Plietker +7 more
TL;DR: TBA[Fe] catalyzes the rearrangement of vinyl and arylcyclopropanes under thermal or photochemical conditions.
Journal ArticleDOI
Fe-Catalyzed Cycloisomerization of Aryl Allenyl Ketones: Access to 3-Arylidene-indan-1-ones.
Johannes Teske,Bernd Plietker +1 more
TL;DR: A cycloisomerization of aryl allenyl ketones to 3-arylidene-indan-1-ones using a cationic Fe-complex as a catalyst is reported, opening a synthetically interesting reaction pathway to this surprisingly underrepresented class of indanones that are not accessible using alternative catalytic systems.
Journal ArticleDOI
A Redox-Neutral Fe-Catalyzed Cycloisomerization of Enyne Acetates
Johannes Teske,Bernd Plietker +1 more
TL;DR: The cationic complex [(Ph3P)2Fe(CO)(NO)]BF4 catalyzes the redox-neutral cycloisomerization of enyne acetates to diastereomerically pure allenyl pyrrolidines in good to excellent yields.
