PhD Exam, September 2021

Andreas successfully passed his final PhD Exam. Congratulations!

J. Mater. Chem. C

„Our recent Paper “Nitrile-Substituted 2-(Oxazolinyl)-Phenols: Minimalistic Excited-State Intramolecular Proton Transfer (ESIPT)-Based Fluorophores” was among the most popular articles in 2020 in Journal of Materials Chemistry C. Great Job Dominik!”

Org. Lett.

Andreas‘ and Thomas work describingg the synthesis of novel iodolopyrazoliums has just been published in Org. Lett.

Congratulations!

Org. Lett. 2020, 22, 7261-7266.  DOI: 10.1021/acs.orglett.0c02593

Chem. Commun.

Dominik’s work about highly tunable ESIPT-luminophores was just published in Chemical Communications. Great collaboration with Pascal Rusch and Prof. Nadja Bigall from the University of Hannover.

Great Job!

Chem. Commun. 2020, 56, 15430-15433. DOI:10.1039/DOCC05780K

ACS Catalysis

Ayham’s article “An Enantioconvergent Benzylic Hydroxylation Using a Chiral Aryl Iodide in a Dual Activation Mode” just appeared on ACS Catalysis. It is the first enantioconvergent hydroxylation ever described. This synthetic catalyst outperforms even enzymes in direct benzylic hydroxylations regarding reactivity and enantioselectivity. Great Job!”

The inside cover picture, provided by Pericàs and Nachtsheim, illustrates the development of novel C1-symmetric iodoarenes as precursors for chiral aryl-λ3-iodanes. The synthesis of these structures is highly modular and allows easy modification on all major substituents, namely the arene, the alkyl ether and the terminal triazole. This is not only the first example for a triazole-based chiral iodoarene but also the so far most efficient C1-symmetric catalyst for the oxidative enantioselective spirocyclization of 1-naphtholcarboxylic acids to spirolactones.

C−H Activation Directing groups are crucial in transition metal-catalyzed C−H activations to control regio-and stereoselectivity. So far, free amines have rarely been used as directing groups since they tend to deactivate the transition metal or undergo undesired side reactions. We demonstrate that free amines in anilines can be used as directing groups in delicate C−H activating alkynylations to give versatile 1,3-enynes in excellent yields and stereoselectivities using highly reactive hypervalent iodine-based alkynylation reagents .
