Abstract It is shown that the interaction of 1-acylamino-2,2-dichloroethenyl(triphenyl)-phosphonium chlorides with alkanolamines having a primary amino group results in the formation of 4-oxazolylphosphonium salts containing hydroxyalkylamine substituents at position 5 of the oxazole cycle. Under similar conditions the reaction of N-substituted alkanolamines with 1-acylamino-2,2-dichloroethenyl-(triphenyl)phosphonium chlorides leads to the formation of 1,3-oxazolidin-2-ylidene derivatives, in which the triphenylphosphonium group is located in the side chain. The structure of the new synthesized compounds has been reliably proven by elemental analysis, IR, 1Н, 13С, 31Р NMR spectroscopy, mass spectrometry and single crystal X-ray diffraction.

1-酰基氨基-2,2-二氯乙烯基（三苯基）氯化鏻与链烷醇胺的相互作用

摘要 研究表明，1-酰氨基-2,2-二氯乙烯（三苯基）氯化鏻与具有伯氨基的链烷醇胺的相互作用导致在恶唑环的 5 位形成含有羟烷基胺取代基的 4-恶唑基鏻盐。在类似条件下，N-取代链烷醇胺与 1-酰氨基-2,2-二氯乙烯基-（三苯基）氯化鏻反应生成 1,3-恶唑烷-2-亚基衍生物，其中三苯基鏻基团位于侧链。新合成化合物的结构已通过元素分析、IR、1Н、13С、31Р NMR 光谱、质谱和单晶 X 射线衍射得到可靠证明。图形概要
