iron‐based metal–organic framework, [Fe(BTC)] (BTC: 1,3,5‐benzenetricarboxylate) is an efficient catalyst in the ring opening of styrene oxide with alcohols and aniline under mild reaction conditions. Out of the various alcohols tested for ring opening of styrene oxide, methanol was found to be the most reactive in terms of percentage conversion and reactivity. The rate of the ring‐opening reaction of
铁基金属有机骨架[Fe(BTC)](BTC:1,3,5-苯三羧酸酯)是在温和的反应条件下,苯乙烯氧化物与醇和苯胺开环的有效催化剂。在测试的各种用于氧化苯乙烯开环的醇中,就百分比转化率和反应性而言,发现甲醇是最活泼的。环氧乙烷的开环反应速率随醇大小的增加而降低,表明活性位点在微孔中的位置。[Fe(BTC)]是真正的多相催化剂,可以重复使用而不会损失活性。类似化合物[Cu 3(BTC)2尽管活性比[Fe(BTC)]低一些,但]也被认为是有效的。将当前的多相方案与均相催化剂进行比较,以深入了解反应机理。
