Application
The Borane diphenylphosphine complex, appearing as a white to off-white powder or crystals, serves as a versatile reactant in various chemical processes. It is instrumental in nucleophilic addition reactions as an anion and plays a crucial role in catalytic dehydrogenation when used with ruthenium bidentate phosphine complexes. Additionally, this complex is involved in deprotonation reactions and facilitates catalytic coupling with alkynyl bromides. It is also effective in catalyst-free Staudinger ligation, an indirect method for 18F-radiolabeling. Furthermore, it aids in the preparation of chiral phosphine-phosphite bidentate ligands with a biphenyl backbone and engages in reactions with frustrated Lewis pair combinations involving group 14 triflates and sterically hindered nitrogen bases.
