New Approaches for Creating New Phosphines and Their Applications

Due to the importance of organophosphines as ligands for transition metal catalysts, development of efficient methods for the synthesis of new phosphines is very important. We recognized 1-alkynylphosphines and their derivatives as useful precursors for creation of new phosphines. Chemical modifications of the carbon-carbon triple bonds, including nucleophilic addition and cycloaddition, led to a wide range of new useful phosphines that are otherwise difficult to synthesize.
