Oxidative cracking reaction of alkenes is applied not only in the synthesis of carbonyl compounds, but also in biomass conversion and degradation of organic pollutants. It is an organic chemical reaction with potential industrial application value. Developing a suitable catalyst to promote the reaction using molecular oxygen as a cheap and safe oxidant under mild conditions is a meaningful research topic in the interdisciplinary field of organic chemistry and material chemistry. In this work, Se/Fe/PCN catalyst was designed and prepared. The experimental results showed that the material was of excellent catalytic activity for the oxidative cracking of styrene derivatives. Notably, the selectivity of the reaction is good, and the selectivity of aldehydes in the product could reach 70%~90%. The catalyst was magnetically separable, and could be reused for the next turn of reaction.

Key words: selenium, iron, oxidative cracking, alkene, carbonyl
