A new route to phosphines was developed by a method that features a “pre-join and transform” process that proceeds via acylphosphine intermediates that may be readily prepared from carboxylic acids and disubstituted phosphines. The efficient decarbonylations of these acylphosphines using a nickel catalyst delivered the corresponding phosphines. This method shows that the carboxyl group can play a role
通过一种具有“预连接和转化”过程的方法,开发了一种新的膦路线,该过程通过可容易地由羧酸和二取代的膦制备的酰基膦中间体进行。使用镍催化剂对这些酰基膦进行有效的脱羰,可得到相应的膦。该方法表明,羧基可起到类似于卤化物或三氟甲磺酸酯的作用,以将取代的磷原子引入芳环。
