    • Phosphines that resulted only in the oligomerization of the allenoate 1a without incorporation of benzylidenemalononitrile 2a (DCM, rt; or benzene, reflux) included Bu3P, Bn3P, Me3P, Me2PhP, MePh2P, P(OEt)3, 4-CF 3C6H4)3P, 3,5-FC6H 3)3P, and BtNAP. DABCO, Et3N, and DBU were not effective catalysts for the desired transformation
