Synthesis and Coordination of Isomeric Phosphinoferrocene Sulfonates

Popis výsledku v původním jazyce

Two isomeric phosphinoferrocene sulfonic acids representing methylene congeners of 1&apos;-(diphenylphosphino)ferrocene-1-sulfonic acid, viz. Ph2PCH2fcSO3H (HL1) and Ph2PfcCH2SO3H (HL2, fc = ferrocene-1,1&apos;-diyl) are synthesized and isolated as the stable crystalline ammonium salts (Et3NH)L1 and (Et2NH2)L2. Additional salts with 1,4-diazabicyclo[2.2.2]octane (dabco), namely, (dabcoH2)(L1)2 and (dabcoH)L2, are prepared for structural characterization by single-crystal X-ray diffraction analysis. Salts (Et3NH)L1 and (Et2NH2)L2 are further studied as ligands in palladium(II) complexes containing the [2-(dimethylamino-κN)methyl]phenyl-κC(1) (L(NC)) auxiliary ligand. With [(L(NC))Pd(μ-Cl)]2, the salts reacted under cleavage of the dimeric precursor to produce anionic phosphine complexes (Et3NH)[(L(NC))PdCl(L1-κP)] and (Et2NH2)[(L(NC))PdCl(L2-κP)]. Subsequent chloride removal with AgNO3 or, alternatively, the direct reaction of (Et3NH)L1 and (Et2NH2)L2 with the acetate-bridged dimer [(L(NC))Pd(μ-OAc)]2 afforded the corresponding neutral phosphinosulfonate complexes that crystallized as the cyclic O,P-bridged trimer [(L(NC))PdCl(μ(P,O)-L1)]3 and hexamer [(L(NC))PdCl(μ(P,O)-L2)]6, respectively. This behavior highlights the hybrid and hemilabile nature of the heteroditopic phosphinosulfonate donors in reactions with the soft Pd(II) ions.
