Separate focus on the oligomerization and oxidative cyclization steps required for the synthesis of 5,10,15-tris(trifluoromethyl)corrole revealed [bis(trifluoroacetoxy)iodo]benzene (PIFA) as a superior alternative oxidant. Under optimized conditions, the pure free-base corrole was obtained with a 6-fold increase in chemical yield and an 11-fold rise in isolated material per synthesis. The corresponding gallium(III) and manganese(III) complexes were isolated by adding the appropriate metal salt prior to corrole purification.
分别关注合成 5,10,15-三（三氟甲基）卟啉所需的低聚和氧化环化步骤，结果表明[双（三氟乙酰氧基）碘]苯（PIFA）是一种优越的替代氧化剂。在优化条件下，纯自由碱卟啉的化学收率提高了 6 倍，每次合成的分离材料增加了 11 倍。通过在卟啉纯化前添加适当的金属盐，可以分离得到相应的镓（III）和锰（III）配合物。
