摘要： A process for the preparation of a phosphorus complex corresponding to the following general formula:
wherein R represents optionally substituted aryl, wherein the substitution may comprise at least one selected from nitro, chloro, fluoro, alkyl, fluoro-alkyl and alkoxy, or optionally substituted alkyl; characterised in that it comprises reacting phosphorus pentachloride and a phosphonic dichloride corresponding to the following general formula:
RPOCl₂
wherein R is as defined above; in the presence of an inert solvent boiling at a temperature of from 120 to 150°C, which is capable of co-distilling a phosphorus oxychloride reaction product, and co-distilling a phosphorus oxychloride reaction product, the molar ratio of phosphorus pentachloride:phosphonic dichloride being from 0.1:1 to 10:1 is disclosed. There is further disclosed a process for chlorinating compounds containing a carbon atom bonded to a hetero-atom selected from oxygen, nitrogen and sulfur which comprises contacting the carbon hetero-atom containing compound with a chloro phosphorus complex corresponding to the following general formula:
wherein R represents optionally substituted aryl or optionally substituted alkyl, so that the hetero-atom is replaced by at least one chlorine atom; the reaction may be extended to compounds containing the carbon to chlorine bond alpha to a carbon atom having at least one hydrogen atom, it may be further dehydrochlorinated by either heating to a temperature of from 50 to 300°C or by reaction with a selected base.摘要翻译： 一种制备对应于下列通式的磷络合物的方法：其中R代表任意取代的芳基，其中取代基可以包括选自硝基，氯，氟，烷基，氟 - 烷基和烷氧基中的至少一种， 或任选取代的烷基; 其特征在于它包括使五氯化磷与对应于以下通式的膦酰氯反应：RPOCl 2，其中R如上定义; 在沸点为120〜150℃的惰性溶剂的存在下，其能够共同蒸馏三氯氧化磷反应产物，并共同蒸馏出三氯氧化磷反应产物，五氯化磷：膦酸的摩尔比 公开了二氯化物为0.1:1至10:1。 还公开了一种氯化含有与选自氧，氮和硫的杂原子键合的碳原子的化合物的方法，该方法包括使含碳杂杂原子的化合物与对应于以下通式的氯磷络合物接触：
其中R表示任选取代的芳基或任选取代的烷基，使得杂原子被至少一个氯原子代替; 该反应可以延伸至含有至少一个氢原子的碳原子的碳与氯键的化合物，也可以通过加热至50至300℃的温度或通过与选定的碱反应而进一步脱氯化氢 。 -
