Phosphines are widely used in organic chemistry as nucleophilic catalysts. The employed phosphines are generally homogeneous, which make the separation of products and recovery of catalysts difficult. To overcome these limitations, heterogeneous supported phosphines as organocatalysts have gradually appeared and have been successfully applied in Baylis-Hillman raction, nucleophilic addition reaction, isomerization of ynones, and hydroxyl protection rection. In this article, the progress on synthesis and organocatalysis of supported phosphine with different grafts is reviewed. The outlook of the research area is provided. ontents
