The reaction of (−)- and (+)-O-ethyl ethylphosphonothioic acid (I) with phosphorus pentachloride has been shown to give optically active O-ethyl ethylphosphonochloridothionate (II) in high yield. For establishing the relative configuration and degree of stereospecificity of (II) use was made of the pyrophosphonothionates, prepared from I and II. The mechanism of the reaction is discussed.
已经显示出(-)-和(+)-O-乙基乙基膦酰基硫代酸(I)与五氯化磷的反应可以高收率得到光学活性的O-乙基乙基膦酰基氯代硫代酸酯(II)。为了确定(II)的相对构型和立体特异性程度,使用了由I和II制备的焦膦酰硫醚酸酯。讨论了反应机理。
