Abstract
The present invention relates to cyclopropane skeleton monophosphine ligands and preparation methods for palladium complexes thereof and an application. Specifically, trans-diaryl substituted cyclopropane skeleton monophosphine ligands are synthesized after trans-1,2-diaryl ethylene undergoing the steps of cyclopropanation reaction, debromination reaction, substitution reaction, and the like. Palladium complexes prepared by coordinating the cyclopropane skeleton monophosphine ligands with a palladium salt show very high activity in catalyzing C—N bond coupling reactions, and have good application prospects.
