描述了金属卟啉如镍、锌、铜和银卟啉向镁卟啉的新转化。通过使用甲苯中的4-甲基苯基溴化镁完成反应。反应的范围很广，得到了各种镁卟啉（见图）。产物，酸敏感镁卟啉，在弱酸性条件下顺利转化为游离碱卟啉。
Novel transformations of metal porphyrins, such as nickel, zinc, copper, and silver porphyrins, to magnesium porphyrins are described. The reactions were accomplished by using 4‐methylphenylmagnesium bromide in toluene. The scope of the reactions was wide and various magnesium porphyrins were obtained (see figure). The products, acid‐sensitive magnesium porphyrins, were smoothly converted to free‐base porphyrins under weakly acidic conditions.
