Polyfunctional ligands: comparative oxidative coupling of [E(PPh2)2](E = CH, N) with iodine

Abstract
Iodine oxidation of the isoelectronic anions [N(PPh2)2] and [HC(PPh2)2] affords the structurally characterized P–P coupling product Ph2P–NPPh2–PPh2 N–PPh2 and the P–C coupling product (Ph2P)2CPPh2–CH2–PPh2, respectively; the P–P heterocoupling product Ph2P–NPPh2–PPh2 CH–PPh2 is obtained in the cross-coupling experiment of Li[N(PPh2)2] and Li[HC(PPh2)2] with iodine at –40 °C.
