摘要：

Iodine oxidation of the isoelectronic anions [N(PPh(2))(2)](-) and [HC(PPh(2))(2)](-) affords the structurally characterized P-P coupling product Ph(2)P-N=PPh(2)-PPh(2)=N-PPh(2) and the P-C coupling product (Ph(2)P)(2)C=PPh(2)-CH2-PPh(2), respectively; the P-P heterocoupling product Ph(2)P-N=PPh(2)-PPh(2)=CH-PPh(2) is obtained in the cross-coupling experiment of Li[N(PPh(2))(2)] and Li[HC(PPh(2))(2)] with iodine at -40 degrees C.
