title: Synthesis and derivatization of highly-functionalized λ⁵-phospholes.
abstract: A variety of λ(5)-phosphole derivatives bearing up to three distinct peripheral functionalities have been prepared by regiospecific [3+2] cycloaddition reactions of the diphosphinoketenimine (PPh2)2C=C=NtBu (1) with electron-poor alkenes. Selective derivatization of the exocyclic functional groups, including formation of dimetallic complexes with a phosphole core, was subsequently accomplished.
