氯化铁可用于催化： 格里纳德氏化合物的制备，如1-萘基氯化镁。 在丙酮肟存在下，将2,4,6-三甲基苯酚（2,4,6-TMP）选择性氧化生成3,5-二甲基-4-羟基苯甲醛（DMHB）。 用FeCl2 改性的Raney型催化剂可以催化α,β-不饱和醛的增强选择性氢化反应生成不饱和醇。 Iron(II) chloride can be used to catalyze: The preparation of Grignard compounds, such as 1-naphthylmagnesium chloride. The selective oxidation of 2,4,6-trimethylphenol (2,4,6-TMP) to 3,5-dimethyl-4-hydroxybenzaldehyde (DMHB) in the presence of acetoxime. Raney-type catalysts modified with FeCl 2 show enhanced selective hydrogenation of an α,β-unsaturated aldehyde to an unsaturated alcohol.
