Description

This trifluoromethylated sulfonamide features a sterically shielded dioxaphosphepin core, delivering exceptional stability and selective reactivity. The electron-deficient trifluoromethyl group enhances electrophilicity, while the bulky isopropyl-substituted aryl moieties prevent unwanted side reactions. Ideal for catalytic transformations requiring high functional group tolerance under standard bench conditions.

Application

1,1,1-Trifluoro-N-[(11bS)-4-oxido-2,6-bis[2,4,6-trisisopropylphenyl]dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-yl]methanesulfonamide serves as a sterically hindered, bench-stable phosphine oxide reagent that facilitates stereoselective coupling reactions. Its rigid, electron-deficient dioxaphosphepin core enables efficient P–N bond formation and functions as a robust ligand in transition-metal catalysis. The trifluoromethyl sulfonamide group enhances solubility and aids purification, while the bulky aryl substituents provide exceptional steric protection and resistance to oxidation.
