Syntheses of the allene complexes (POCOP)Ir(?2-RC=.=CR') (2-Oct , R = C3H7, R' = C2H5; 2-Hex , R = C2H5, R' = CH3; POCOP = 2,6-bis(di-tert-butylphosphonito)benzene) by isomerization from internal alkynes are reported. We will present our progress towards the development of a catalytic alkyne to allene methodology. The potential use of this catalyst system in the synthesis of natural products will also be discussed.
