  摘要：

  Generation of C,N-dianions (2) of 2-methylbenzenesulfonamides (1) followed by addition of N,N-dimethylcarbamoyl chloride gave 2-(N,N-dimethylcarbamoyl)methylbenzenesulfonamides (3), which were cyclized to 3,4-dihydro-2H-1,2-benzo[e]thiazin-3-one 1,1-dioxides (5). 3-Dimethylamino-2H-1,2-benzo)[e]thiazine. 1,1-dioxides (7) were obtained in one step by the reaction of 2 with N,N-dimethylthiocarbamoyl chloride. On the other hand, the reaction of 2 with N,N-dimethylsulfamoyl chloride yielded 2,2 ' -ethylene-bis(benzenesulfonamide)s (10) and / or 2,3-dihydro-1,2-benzothiazole 1,1-dioxides (11).

  摘要：

  在固态下测得的某些N-酰基-N-取代磺酰胺衍生物的羰基吸收分裂现象以及S-N伸缩振动向长波长区域的位移均有所描述。三级磺酰胺的SO2伸缩振动比二级磺酰胺位于更短的波长区域。N-乙酰基-N-烷基甲烷(或乙烷)磺酰胺在约1125cm-1处显示出强烈的N-CH2-R基团的C-N伸缩振动。N-酰基-N-取代磺酰胺衍生物在1250∼1290cm-1处具有非常强烈的C-CO-N基团的不对称伸缩振动。此外，还描述了一些磺酰胺衍生物的合成。

  A robust transition-metal-free one-step strategy for the synthesis of ynamides from sulfonamides and (Z)-1,2-dichloroalkenes or alkynyl chlorides is presented. This method is not only effective for internal ynamides but also amenable for terminal ynamides. Various functional groups, even the vinyl moiety, are compatible, and thus, this strategy offers the opportunity for further functionalization.
