    N,N′-Bis(diphenylphosphino)diaminophenylphosphine Ligands for Chromium-Catalyzed Selective Ethylene Oligomerization Reactions
    摘要:
    Reaction of 1 or 2 equiv of Ph2PCl with PhP(N(H)R)(2) (R = n-propyl) yields Ph2PN(R)P(Ph)N(R)H (1) or Ph2PN(R)P(Ph)N(R)PPh2 (2), respectively. In contrast, reaction of 1 or 2 equiv of Ph2PCl with PhP(N(H)R)(2) (R = isopropyl) yields exclusively Ph2PN(R)P(Ph)N(R)H (3), even under more forcing conditions. Low-temperature NMR spectroscopy and a conformational analysis of Ph2PN-(iPr)P(Ph)N(iPr)H (3) reveal the lowest energy conformer to have a close N-H center dot center dot center dot P interaction of 2.95 angstrom, which we speculate may hinder further reactivity of this molecule. Reaction of 3 with [Cr(CO)(6)] yields [Cr(3)(CO)(4)] (5), which has been structurally characterized. Coordination of ligand 3 facilitates its conversion to Ph2PN(iPr)P(Ph)N(iPr)PPh2 (4) while bound to chromium, yielding the complex [Cr(4)(CO)(4)] (6), which has also been structurally characterized. Ligands 1 and 2, when reacted in situ with [Cr(acac)(3)] (acac = acetylacetonate) and modified methylalumoxane, and complexes 5 and 6, when activated with Ag[Al(OC4F9)(4)] and triethylaluminum, are moderately active and selective catalysts for the selective oligomerization of ethene to 1-hexene and 1-octene.
