  Novel phosphine ligands bearing 3(5)-pyrazolyl and 4-(2-amino)pyrimidinyl groups: Synthesis and coordination chemistry

  摘要：

  Novel triphenyl phosphine ligands bearing pyrazole or 2-aminopyrimidine groups in the ortho or meta position of one or three of the phenyl rings were obtained starting from the corresponding acyl derivatives Ph2P(o-C6H4-COCH3), Ph2P(m-C6H4-COCH3), Or P(m-C6H4-COCH3)(3)- Conversion of the acyl groups into 3-dimethylamino-2-propen-l-onyl units was achieved by reaction with HC(O-Me)(2)NMe2 which underwent ring closing with hydrazine or guanidine to yield the desired heterocycles. Two palladium complexes were synthesized using the coordinatively labile precursor (PhCN)(2)PdCl2, one of them could be characterized by X-ray structure analysis. (c) 2005 Elsevier B.V.

  A Fully Integrated High-Throughput Screening Methodology for the Discovery of New Polyolefin Catalysts:  Discovery of a New Class of High Temperature Single-Site Group (IV) Copolymerization Catalysts

  摘要：

  For the first time, new catalysts for olefin polymerization have been discovered through the application of fully integrated high-throughput primary and secondary screening techniques supported by rapid polymer characterization methods. Microscale 1-octene primary screening polymerization experiments combining arrays of ligands with reactive metal complexes M(CH2Ph)(4) (M = Zr, Hf) and multiple activation conditions represent a new high-throughput technique for discovering novel group (IV) polymerization catalysts. The primary screening methods described here have been validated using a commercially relevant polyolefin catalyst, and implemented rapidly to discover the new amide-ether based hafnium catalyst [eta(2)-(N,O)-(2-MeO-C6H4)(2,4,6-Me3C6H2)N]Hf(CH2Ph)(3) (1), which is capable of polymerizing 1-octene to high conversion. The molecular structure of I has been determined by X-ray diffraction. Larger scale secondary screening experiments performed on a focused 96-member amine-ether library demonstrated the versatile high temperature ethylene-1-octene copolymerization capabilities of this catalyst class, and led to significant performance improvements over the initial primary screening discovery. Conventional one gallon batch reactor copolymerizations performed using selected amide-ether hafnium compounds confirmed the performance features of this new catalyst class, serving to fully validate the experimental results from the high-throughput approaches described herein.
