Aromatic and aliphatic N-sulphinyl amines add smoothly to diphenyl and biphenylene ketene forming substituted 1,2-thiazetidinone-(3)-oxides-(1). An addition of ketene itself to N-sulphinyl cyclohexyl amine can be concluded from secondary products only.

The aminolysis process of sulfinamoyl derivatives was investigated with sulfinamoyl esters. An intermediate sulfine was unambiguously evidenced by formation of a Diels-Alder type adduct. The aminolysis leads to final thiooxamate products. A carbophilic addition was suggested for the reaction with secondaryamines. With sulfinamoyl, -sulfones and -sulfonamides, a thiourea is formed resulting from a

we report a combined experimental and theoreticalstudy on the molecular structure and vibrational spectra of m- chlorosulfinylaniline. The substance was characterized by 1 H and 13 C NMR and GC-mass spectrometry as well as by FT-IR and Raman spectroscopy. Experimental results were complemented with theoretical calculations at the B3LYP and MP2 levels of theory for electronic structure and harmonic
摘要 在目前的工作中,我们报告了对间氯亚磺酰基苯胺的分子结构和振动光谱的联合实验和理论研究。该物质通过 1 H 和 13 C NMR 和 GC-质谱以及 FT-IR 和拉曼光谱表征。实验结果补充了 B3LYP 和 MP2 理论水平的理论计算,用于电子结构和谐振子,以及振动结构理论的振动自洽场水平。发现观察到的和计算出的频率非常一致。自然键轨道分析解释了分子在电荷离域时的稳定性及其电子特性。

Palladium-catalyzed [3+2] annulation of N-sulfinylanilines with vinylethylene carbonates and vinyl epoxides has been reported, affording the 1,2,3-oxathiazolidine-2-oxides under mild reaction conditions. Further synthetic applications of 1,2,3-oxathiazolidine-2-oxides in the preparation of sulfoxides, β-amino alcohols and amines have also been demonstrated.
