Description

This xanthene-based bisphosphine features two sterically shielded di-tert-butylphosphine units anchored to a rigid, electron-rich xanthene core. The bulky tert-butyl groups confer exceptional steric protection and enhance stability under air and moisture. Designed for demanding catalytic applications, it integrates readily into palladium and nickel systems, enabling efficient cross-coupling reactions with minimal decomposition.
