摘要: The reaction of p-phenylenediamine with excess PCl 3 in the presence pyridine affords p-C 6H 4[N(PCl 2) 2] 2 ( 1) good yield. Fluorination 1 SbF produces 4[N(PF 2). aminotetra(phosphonites) 4[N{P(OC 4OMe- o) 2} 3) and 4[N{P(OMe) 4) have been prepared by reacting appropriate amount 2-(methoxy)phenol or methanol, respectively, triethylamine. reactions 4 H 2O 2, elemental sulfur, selenium afforded tetrachalcogenides, 4[N{P(O)(OC 5), 4[N{P(S)(OMe) 6), 4[N{P(Se)(OMe) 7) Reactions [M(COD)Cl (M = Pd Pt) (COD cycloocta-1,5-diene) resulted formation chelate complexes, [M 2Cl 4- 4{N{P(OC 8, M 9, Pt). equiv CuX (X Br I) produce tetranuclear [Cu 4(mu 2-X) 4(NCCH 4{N(P(OC 10, X Br; 11, I). molecular structures 1- 3, 6, 7, 9- 11 are confirmed single-crystal X-ray diffraction studies. weak intermolecular P...P interactions observed leads to a 2D sheetlike structure, which is also examined DFT calculations. catalytic activity Pd(II) 8 has investigated Suzuki-Miyaura cross-coupling reactions.
