Donor/donor carbenes are relatively new in the field of carbene chemistry; although
applications in C− H and X− H insertion reactions are few in number, they demonstrate …

Metal carbenes usually possess versatile reactivities that are controlled by the presence of
both the metals and the ligands. Diazo compounds are commonly used for the generation of …

N-Sulfonyl hydrazones have been extensively used as operationally safe carbene
precursors in modern organic synthesis due to their ready availability, facile …

Eine Frage des Katalysators: Azolverbindungen können mit N‐Tosylhydrazonen, die
nichtaktivierte Alkylgruppen tragen, direkt alkyliert werden (siehe Schema; phen= 1, 10 …

The first enantioselective intramolecular C− H insertion and cyclopropanation reactions of
donor‐and donor/donor‐carbenes by a nondiazo approach are reported. The reactions …

Although transition-metal-catalyzed B–H bond insertion of carbenes into stable borane
adducts has emerged as a promising method for organoborane synthesis, all the diazo …

Herein, we report a transition-metal-free C–H bond sulfoximidation protocol of sulfonyl
hydrazones with hypervalent iodine (III) reagents. A library of novel N …

Transition‐metal‐catalyzed reactions of N‐tosylhydrazones provide a convenient access to
various molecules by novel carbon‐carbon or carbon‐heteroatom bond formations via …

The metal-catalyzed carbenoid-based N–H insertions of α-stabilized diazo compounds and
relative precursors serve as robust strategies for the formation of C–N bonds. However …

Metallcarbene sind vielseitige Verbindungen, deren Reaktivität sowohl durch das Metall als
auch den Liganden gesteuert werden kann. Zur Synthese von Metallcarbenen nutzt man im …
