在Pd(PPh3)4催化下,以K3PO4为碱,以二氧六环为溶剂,二茂铁硼酸和有机三氟甲磺酸酯在回流条件下高收率得到了单取代二茂铁的偶联产物.不同三氟甲磺酸酯的偶联反应产率在72%～92%之间.
Under the catalysis of Pd (PPh3) 4, K3PO4 was used as the base and dioxane was used as the solvent. Ferroceneboronic acid and organotrifluoromethanesulfonate gave high yields of monosubstituted ferrocene under high reflux conditions The yield of coupling reaction of different triflates was between 72% ~ 92%.
