| abstract |
The invention provides a thiourea nitrogen phosphine ligand, a preparation method and application thereof, and the structural formula of the ligand is: The thiourea nitrogen phosphine ligand is obtained by reacting aryl amine and aryl isothiocyanate to obtain aryl thiourea, and then reacting with disubstituted phosphine. The obtained thiourea-type phosphine nitrogen ligand can be used for the telomerization reaction of 1,3-butadiene and nucleophile, which not only greatly reduces the amount of metal catalyst, but also has high conversion rate and good selectivity. |
