摘　　要：By introducing hydroxyl group into PPh3 ligand,a promoter-free palladium catalytic system based on(p-HOC6H4)PPh2 ligand was developed for the telomerization of 1,3-butadiene with CO_(2).High activity and selectivity towards CO_(2)-incorporated divinylδ-lactone monomer were achieved(TON/TOF:up to 4540/568 h–1;selectivity ofδ-lactone and its isomers:up to 97%).The key role of phenolic hydroxyl group of the ligand in attaining high activity was validated.The good performance of large-scale reaction in batch reactor demonstrated the potential utility of this simple catalytic system in valorizing CO_(2) with bulk chemical feedstock.
