title: Synthesis of phosphabenzenes by an iron-catalyzed [2+2+2] cycloaddition reaction of diynes with phosphaalkynes.
abstract: A method for the synthesis of phosphabenzenes under iron catalysis is described. Thus, the FeI2 -catalyzed [2+2+2] cycloaddition of diynes with phosphaalkynes in m-xylene gave a variety of phosphabenzenes in good to high yields (up to 87 % yield).
