Description
技术领域
本发明属于有机合成领域,涉及一类有机膦化合物的合成方法,尤其涉及有机氧膦类化合物的合成方法。
技术背景
有机氧膦类化合物是一种重要的化学合成中间体,广泛应用于工业生产中,例如各种农药以及手性膦配体的合成,其可替代碱金属氰化物作为杂环化合物合成的偶联剂。目前有机氧膦类化合物的合成方法主要有3种:1)以POCl3为原料,经傅克烷化反应后,利用氢化铝锂作为还原剂还原中间产物后得到有机氧膦类化合物;2)是以亚磷酸二乙酯为原料,与相应的格氏试剂反应生成目标产物(Organometallics(2010),29(17),3936-3950);3)以PCl3为原料,经傅克烷化反应后,再经适当的水解得到目标产物(Chemistry-AEuropean Journal,10.1002/chem.202200507),但其中间体Ph2PCl的纯化较为困难,仅以37.0%的收率得到目标产物。而且目前工业生产的方法中普遍存在生产试剂昂贵,生产条件苛刻,并且要求在绝对无水、无氧的条件下进行,一定程度上限制了有机氧膦类化合物的大规模生产。因此,探索并改进有机氧膦类化合物的合成方法,开发操作相对简单、成本较低的工艺路线,具有一定的实用意义。
发明内容
本发明的目的在于提供一种收率高,反应条件温和,操作简单的合成有机氧膦类化合物新方法。
为了实现上述目的,本发明反应路线如下:
在氩气保护下,向干燥反应器中加入反应溶剂四氢呋喃,然后加入烷烃或芳烃类化合物,搅拌均匀后加入亚磷酸,再加入路易斯酸催化剂,加热回流,反应结束后停止反应,经淬灭,过滤,干燥得到有机氧膦类化合物;
所述的烷烃或芳烃类化合物为金刚烷、环己烷或苯;所述路易斯酸为:氯化铝、氯化铁或三氟化硼;所述的烷烃或芳烃类化合物、亚磷酸及路易斯酸催化剂的摩尔比为1:0.5~0.8:0.1~0.2。
反应时间为6-8h。
本发明有益效果在于:避免危险性较高的氢化铝锂的使用、避免了多步反应,采用廉价易得的亚磷酸及烷烃或芳烃类试剂,直接一步法合成目标产物,反应温度较低,反应条件更加温和,操作更加简便,收率可达90%以上,非常有利于实际工业化生产。
