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 (COD)Rh and (CO)2Rh complexes of the new NHC have been prepared and fully characterised including X-ray diffraction studies. Spectroscopic and structural
从1,2,4-苯并噻二嗪-1,1-二氧化物制备了具有环状磺酰胺结构基序的第一个N-杂环卡宾1。在六元杂环内,卡宾C原子与氨基和磺酰胺基键合。新型NHC的(COD)Rh和(CO)2 Rh配合物已经制备并进行了全面表征,包括X射线衍射研究。光谱和结构数据表明,1总体上是较差的供体(TEP:2063 cm -1),并且其供体/受体性质接近于相关的环状羧酰胺取代的羧苯。
