Direct Access to Allenylphosphine Oxides via a Metal Free Coupling of Propargylic Substrates with P(O)H Compounds

A direct and convenient approach for the coupling of propargylic substrates with diphenylphosphine oxide in the presence of Tf2O and 2,6-lutidine has been developed. The method provides a general approach for the construction of attractive allenylphosphoryl skeletons with high atom and step economy under metal free conditions.

Radical cyclizations of functionalized allenes

Substitution of P(O)Ph2, SOPh, and SO2Ph on an allene facilitates intramolecular radical addition to the central allene carbon to provide good yields of five-, six-, and seven-membered carbocycles.
