First Part: Syntheses of Diarylamidophosphino Nickel(II) Complexes and reactivity study
We have synthesized [Me-NP-iPr]Ni(CH2SiMe3)(L)(L=2,6-lutidine). In order to compare with [Me-NP-iPr]Ni(CH2SiMe3)(L)(L= pyridine, 2,4lutidine, PMe3), benzene C-H activation reaction experiment were carried out and rate constant were determined by kinetic study. We also synthesized [Me-NP-iPr]Ni(Ph)(2,6-lutidine) to prove the benzene C-H activation product by the trimethylsilylmethyl substituted Ni complex. Solution structure of [Me-NP-iPr]Ni(R)(L)(L=2,6-lutidine; R= CH2SiMe3, Ph) and Solid structure of [Me-NP-iPr]Ni(R)(L)(L=2,6-lutidine; R= Cl, Ph) were characterized by NMR spectroscopy and X-Ray diffraction.
Second Part: Syntheses of Diarylamidophosphino Zirconium(IV) Complexes and reactivity test
Use [iPr-PNP]Zr(=CHSiMe3)(Cl) as starting material to react with PhMgCl yield [iPr-PNP]Zr(=CHSiMe3)(CH2SiMe3). Solution and Solid structure of [iPr-PNP]Zr(=CHSiMe3)(CH2SiMe3) were characterized by NMR spectroscopy and X-Ray diffraction. Experiments for inducing intramolecular £\-H abstruction to afford [iPr-PNP]Zr(¡ÝCHSiMe3)(L)(L= solvent) were unsuccessful. Attempt to oxidize trimethylsilylmethyl substitution with [PhNHMe2]+[B(C6F5)4]- resulting protonated product {[iPr-PNP]Zr(CH2SiMe3)2}+{B(C6F5)4}-, solution and solid structure were also characterized.
