substituted by four –CH2PPh2 pendant arms was synthesised starting from a generic C5-resorcinarene. Combining this tetraphosphine with palladium acetate and Cs2CO3 gave an active Heck catalyst. The highest activities were observed by using a tetraphosphine/Pd ratio of ca. 1:1.
从一个通用的C 5-间苯二芳基开始合成被四个-CH 2 PPh 2侧链取代的间苯二芳基空洞。将此四膦与
醋酸钯Cs 2 CO 3得到活性的Heck催化剂。通过使用约4的四膦/ Pd比观察到最高的活性。1:1
