NEt3 afforded trans-[Pd(κ2-Sac-CH2O)2]. Further reaction of [Pd(κ2-Sac-CH2O)2] with one equivalent of diphosphine (L2), Ph2P(CH2)nPPh2, (n = 1, dppm; 2, dppe and 3, dppp), Ph2P(S)(CH2)P(S)Ph2 (dppmS2) or Ph2P(O)(CH2)2P(O)Ph2 (dppeO2) afforded mixed ligand complexes [Pd(κ1-Sac-CH2O)2(L2)], while reaction with two equivalents of Ph3P, Ph3PO or Ph3PS (L) gave trans-[Pd(κ1-Sac-CH2O)2(L)2]. The N-hydro
Na2PdCl4 与两当量的 N-羟甲基糖精 (Sac-CH2OH) 在 NEt3 存在下反应得到反式-[Pd(κ2-Sac-CH2O)2]。[Pd(κ2-Sac-CH2O)2] 与一当量的二膦 (L2), Ph2P(CH2)nPPh2, (n = 1, dppm; 2, dppe and 3, dppp), Ph2P(S)( CH2)P(S)Ph2 (dppmS2) 或 Ph2P(O)(CH2)2P(O)Ph2 (dppeO2) 提供混合配体复合物 [Pd(κ1-Sac-CH2O)2(L2)],同时与两个当量反应Ph3P、Ph3PO 或 Ph3PS (L) 产生反式-[Pd(κ1-Sac-CH2O)2(L)2]。N-羟甲基糖精阴离子作为单齿配体,通过羟甲基氧原子与钯中心配位。通过物理化学和光谱方法对复合物进行了表征。此外,在体外筛选了游离配体 N-羟甲基糖精和一些复合物的抗菌活性。
