    • I2 reacts stoichiometrically with LiN(PPh2) 2 to effect P-P coupling; Braunstein, P, Hasselbring, R, Tiripicchio, A, Ugozzoli, F. J. Chem. Soc, Chem. Commun. 1995, 37-38. We have also confirmed that I2 is consumed quantitatively by both our phosphinoamines and our zirconium phosphino-amide complexes. Stoichiometric reaction of Ph2PNHiPr with I2 in C6D6 leads to complete consumption of both I2 (based on disappearance of the diagnostic purple color) and Ph 2PNHiPr (based on disappearance of its 31P NMR signal) to form a highly insoluble red/orange material. Likewise, stoichiometric reaction of 2 with 12 leads to complete consumption of both materials and appearance of new phosphorus-containing products
