Description

This phosphabicyclo[5.3.0]decane features a sterically shielded phosphorus center flanked by electron-rich aryl groups, enabling robust performance in catalytic transformations. The dimethylamino and tetraoxa functionalities enhance solubility and stability under standard conditions.

Application

(1S,7S)-4-Dimethylamino-9,9-dimethyl-2,2,6,6-tetrakis(3,5-dimethylphenyl)-3,5,8,10-tetraoxa-4-phosphabicyclo[5.3.0]decane serves as a sterically encumbered, bench-stable phosphine reagent enabling efficient coupling reactions in synthetic workflows. Its electron-rich phosphorus center facilitates rapid reductive elimination and exhibits excellent functional group tolerance, making it well-suited for Pd-catalyzed cross-couplings and iterative C–C bond formation. The bulky aryl substituents enhance stability and ease of purification, supporting scalable applications in complex molecule synthesis.
