The first N-heterocyclic carbene 1 featuring a cyclic sulfonamide structural motif has been prepared from 1,2,4-benzothiadiazine-1,1-dioxide. Within the six-membered heterocycle the carbene C atom is bound to an amino and a sulfonamido group. The (CO

Imidazolium and benzimidazolium salts featuring exocyclic N-acyl or N-sulfonyl groups were prepared and converted in situ to the corresponding N-heterocyclic carbenes by deprotonation. The NHCs were further converted to group six adducts (sulfur and

The synthesis of a new mixed amino–amido N-heterocyclic carbene (type A) starting from anthranilic acid is presented. A new straightforward synthetic approach to related diaminocarbenes of type B is also described. Both NHCs react with group 6 elem

The synthesis of novel hexahydrotriazine-based NHCs from easily available starting materials is described. Tribenzyltriazacyclohexane 1 is converted stepwise to the six-membered diamino carbene 3 with a saturated ring structure. Analogously, the cycl
