英文摘要: Abstract(#br)The diphosphine proligand R 2 P(CH 2 ) 5 PR 2 (R = i -Pr) reacts with PdCl 2 or Pd(PhCN) 2 Cl 2 in CH 2 Cl 2 to give the 2:2 adduct trans -{µ-k P ,k P′ -R 2 P(CH 2 ) 5 PR 2 } 2 Pd 2 Cl 4 ( 1 ) featuring a 16-atom chelate ring, along with other uncharacterized species. Treating 1 with AgOTf or heating it in the solid state gave the PC sp3 P-type pincer complexes {k P ,k C ,k P -(R 2 P(CH 2 ) 2 ) 2 CH}PdX (X: OTf, 2 ; Cl, 2-Cl ). Complex 2 was also prepared via a one-pot route by refluxing a mixture of the proligand, PdCl 2 , and AgOTf in toluene. Complexes 1 and 2 have been characterized by NMR spectroscopy, elemental analysis, mass spectrometry and single crystal X-ray analysis.
