  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.

  The invention relates to a method for the manufacture of substituted phosphanes and substituted phosphanes manufactured according to the method. Phosphanes, phosphane oxides, sulfides or selenides are used as ligands in coordination compounds. They play a central role in controlling the activity and selectivity of catalysts. The object is achieved by the invention by synthesizing heterocyclic substituents on aromatic groups by introducing acetyl groups. In this manner, previously unknown representatives of the families of phosphanes, phosphane oxides, sulfides and selenides are made accessible.

  本发明涉及一种制造取代膦和按照该方法制造的取代膦的方法。在配位化合物中，膦、膦氧化物、硫化物或硒化物被用作配体。它们在控制催化剂的活性和选择性方面起着核心作用。本发明通过在芳香族基团上引入乙酰基合成杂环取代基，从而实现了该目标。通过这种方法，膦、膦氧化物、硫化物和硒化物的新的未知代表得以获得。
