Bis(bicyclo[1.1.1]pentyl)chlorophosphine as a Precursor for the Preparation of Bis(bicyclo[1.1.1]pentyl)phosphines.

Dialkylchlorophosphines are among the most versatile building blocks for tertiary phosphine ligands, but their synthesis relies on the nucleophilic substitution of PCl, leaving substituents that require P-H precursors largely inaccessible. The primary phosphine reagent iPrNPH·BH can serve as a doubly protected PHCl proxy, enabling the synthesis of bis(bicyclo[1.1.

Tris(bicyclo[1.1.1]pentyl)phosphine: An Exceptionally Small Tri--alkylphosphine and Its Bis-Ligated Pd(0) Complex.

Tris(bicyclo[1.1.1]pentyl)phosphine can be prepared by radical addition of PH to [1.
