Synthesis of Indenyl Triazenes by Rhodium-Catalyzed Annulation Reactions

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Carl Thomas Bormann, Florian Gérald Abela

The synthesis of vinyl triazenes by metal-catalyzed processes is attractive, but only few examples have been described so far. Here, we describe Rh-catalyzed [3+2] annulation reactions of arylboronic acid derivatives and alkynyl triazenes. These reactions ...

Efficient Kinetic Resolution of Sulfur-Stereogenic Sulfoximines by Exploiting (CpRhIII)-Rh-X-Catalyzed C-H Functionalization

Nicolai Cramer, Marcus Brauns

Chiral sulfoximines with stereogenic sulfur atoms are promising motifs in drug discovery. We report an efficient method to access chiral sulfoximines through a C-H functionalization based kinetic resolution. A rhodium(III) complex equipped with a chiral Cp ...

Nickel-Catalyzed Regioselective Hydroalkylation and Hydroarylation of Alkenyl Boronic Esters

Xile Hu, Srikrishna Bera

Metal hydride catalyzed hydrocarbonation reactions of alkenes are an efficient approach to construct new carbon-carbon bonds from readily available alkenes. However, the regioselectivity of hydrocarbonation remains challenging to be controlled. In nickel h ...

Manganese-mediated reductive amidation of esters with nitroarenes

Xile Hu, Chi Wai Cheung, Peng Wang, Ning Shen

Amides are ubiquitous molecules in nature and in synthetic chemistry. Here we report a convenient and efficient method to synthesize N-aryl amides via amidation of esters with nitroarenes. In the presence of manganese metal, this amidation proceeded smooth ...

Copper-catalyzed remote C(sp3)–H azidation and oxidative trifluoromethylation of benzohydrazides

Qian Wang, Jieping Zhu, Xu Bao

The Hofmann-Löffler-Freytag (HLF) reaction is a prototypical example of radical-based remote functionalization of unactivated C(sp3)–H bond. While 1,5-hydrogen atom transfer (1,5-HAT) of the amidyl radical is thermodynamically favorable and is well-establi ...

Investigations of the Chemistry of 1-Alkynyltriazenes

Florian Gérald Abela

The chemistry of aromatic triazenes is well known, and has been explored for more than a century. These compounds have emerged as very useful intermediates, because of their unique reactivity. This functionality can notably be used to access many other fun ...

Amide synthesis via nickel-catalysed reductive aminocarbonylation of aryl halides with nitroarenes

Xile Hu, Chi Wai Cheung, Marten Leendert Ploeger

Aminocarbonylation of aryl halides is one of the most useful methods in amide synthesis, but nitroarenes have not been used as a nitrogen source in this method even though they are more economical and accessible than anilines. Reported here is the developm ...

Dyes, Radicals and Nitrous Oxide Adducts Derived from N-Heterocyclic Carbenes

Léonard Yannick Maurice Eymann

N-Heterocyclic carbenes are able to form covalent adducts with nitrous oxide (N2O) under ambient conditions. This thesis summarizes the studies of these adducts and their reactivity. A ditopic carbanionic N-heterocyclic carbene was found to react with nit ...

From isonitrile to nitrile via ketenimine intermediate: Palladium-catalyzed 1,1-carbocyanation of ally carbonate by alpha-isocyanoacetate

Qian Wang, Jieping Zhu, Guanyinsheng Qiu, Charlotte Marie Sornay, Sheng-Cai Zheng, David Savary

A palladium-catalyzed 1,1-carbocyanation of allyl carbonate by alpha-quaternary alpha-isocyanoacetate was developed. Formation of ketenimine followed by homolysis of the C-N bond and recombination of the resulting caged radical pair was proposed to account ...

Nickel-Catalyzed Reductive Transamidation of Secondary Amides with Nitroarenes

Xile Hu, Chi Wai Cheung, Marten Leendert Ploeger

Transmidation is an attractive method for amide synthesis. However, transamidation of secondary amides is challenging. Here, we describe a reductive transamidation method that employs readily available nitro(hetero)arenes as the nitrogen sources, zinc or m ...
