Description

This gold(I) complex features a trifluoromethanesulfonyl-imide anion paired with a dicyclohexylphosphino-2',6'-dimethoxy-1,1'-biphenyl ligand, delivering high stability and solubility in polar aprotic solvents. The bulky phosphine moiety enhances steric protection around the gold center, promoting resistance to aggregation and facilitating efficient catalytic turnover in cross-coupling reactions.

Application

Bis(trifluoromethanesulfonyl)imide(2-dicyclohexylphosphino-2',6'-dimethoxy-1,1'-biphenyl)gold(I) serves as a robust, bench-stable catalyst for gold(I)-mediated C–H activation and alkyne functionalization reactions. Its tailored ligand framework enhances reactivity in cycloadditions and cyclizations, enabling efficient construction of complex heterocyclic scaffolds with high functional group tolerance and ease of purification.
