9-Phosphabicyclo[3.3.1]nonane (9-PBN) is the simplest member of a class of phosphorus compounds that can be used as an efficient and economical reagent for cross-coupling reactions in organic synthesis. 9-PBN is a stable, white solid that is soluble in hydrocarbon solvents and reacts with nucleophiles such as amines, alcohols, and thiols to form phosphine oxides (PR 3 ). 9-PBN undergoes rapid isomerization between the cis and trans configurations at room temperature. When heated, it converts to the cis configuration at a rate that depends on the activation energy of the reaction. It has been proposed that this conversion may be catalyzed by acid or base catalysis because of its acidic nature or polydentate ligand properties. 9-PBN has been shown to react with primary alcohols to form amides via nucleophilic attack on
