摘要N-烷基和N,N-二烷基O的新颖合成已经在实验室规模上开发了使用三个氧化系统的二黄原酸二乙酯和伯胺和仲胺生成的乙基硫代氨基甲酸酯,并且已在半工业规模应用了使用次氯酸钠的方法。研究了氧化剂,次氯酸钠,原位生成的过氧乙酸和乙酸锰(II)/氧气体系对产品纯度和收率的影响。将通过这三种方法获得的结果与在硫酸化镍沸石催化剂存在下乙基黄原酸乙酸钠和胺以及乙基黄原酸钠和胺反应得到的结果进行比较。在分离反应中间体并通过傅立叶变换红外光谱测定其结构的基础上,建立了次氯酸钠氧化的反应机理。1 H和13 C NMR以及质谱法。与商业和催化促进的合成方法相比,建议的次氯酸钠和乙酸锰(II)体系具有许多优势,因为它们是新型的生态友好型合成方法。 图形概要

Abstract The complexes [Rh 2 (O 2 CMe) 4 (L) 2 ], in which L = DETC (EtOSCNEt 2 ). ETC (EtOSCNHEt), MTC (EtOSCNHMe) and TC (EtOSCNH 2 ), have been prepared and characterized by elemental analyses and electronic, IR and NMR ( 1 H and 13 C) spectra. The thermal behaviour of these complexes and of the DMTC (EtOSCNMe 2 ), TBA (PhSCNH 2 ) and TAA (MeSCNHPh) analogues is discussed. On heating the DETC and DMTC
