The reaction of [iPr2N=CHCl]Cl with 2-phenylbenzthiazolidine (Ph-BtzH) and subsequent anion metathesis afforded the formamidinium salt [(Ph-Btz)CH(NiPr2)][PF6] ([1aH][PF6]). The reaction of [1aH][PF6] with (Me3Si)2NNa in the presence of grey selenium

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

4-Phenylsemicarbazide and 1,5-diphenylcarbazide are suitable starting materials for the syntheses of N-heterocyclic carbene (NHC) compounds with new backbone structures. In the first case, cyclisation and subsequent methylation leads to a cationic pr

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
