between the labile precursors cis-[Pd(C6F5)2(PhCN)2] or [Pd(C6F5)(tht)(μ-Cl)}2] (tht=tetrahydrothiophene) and the corresponding iminophosphines. Complex (9) undergoes metathetical exchange of chloride with anionic monodentate ligands when reacting with alkaline salts, giving the complexes of formula [Pd(C6F5)X(iPrN–P)] [X=Br (11), I (12), CN (13), SCN (14), SC6H5 (15), p-SC6H4Me (16), p-SC6H4NO2 (17),
摘要:合成了具有混合给体双齿配体o-Ph2PC6H4-CHNR(RN-P)的钯(II)单和双(五氟苯基)衍生物。通式为[Pd(C6F5)2(RN–P)]的新络合物[R = Me(1),Et(2),nPr(3)iPr(4),tBu(5),Ph(6), NH–Me(7)]和[Pd(C6F5)Cl(RN–P)] [R = Me(8),iPr(9),NH–Me(10)]分别通过不稳定的前体顺式[[Pd(C6F5)2(PhCN)2]或[Pd(C6F5)(tht)(μ-Cl)} 2](tht =四氢噻吩)和相应的亚氨基膦。与碱金属盐反应时,配合物(9)与阴离子单齿配体进行氯离子交换,得到式[Pd(C6F5)X(iPrN–P)]的配合物[X = Br(11),I(12),CN (13),SCN(14),SC6H5(15),p-SC6H4Me(16),p-SC6H4NO2(17),OMe(18)]。此
