The synthesis of fluoroalkyl and non-fluorinated long chain alkyl ferrocenylphosphonates of the type FcP(O)(OR)2 (Fc: ferrocenyl; R = CH2CF3 (1), CH2C2F5 (2), Et (3) n-Hex (4), n-Hep (5) and n-Oct (6)) from reaction of ferrocene with corresponding phosphorochloridates is reported. The ferrocenyl phosphonates 1-4 were used as ligands, which reacted with tin(IV) chloride to produce the new complexes
FcP(O)(OR) 2类型的氟代烷基和非氟化长链烷基二茂铁基膦酸酯的合成(Fc:二茂铁基;R = CH 2 CF 3 (1), CH 2 C 2 F 5 (2), Et ( 3) 报道了来自二茂铁与相应的氯化磷反应的 n-Hex (4)、n-Hep (5) 和 n-Oct (6))。二茂铁膦酸酯 1-4 用作配体,与氯化锡 (IV) 反应生成新的配合物 [SnCl 4 (1) 2 ] (7), [SnCl 4 (2) 2 ] (8), [SnCl 4 (3) 2 ] (9) 和 [SnCl 4 (4) 2] (10)。所有这些二茂铁基膦酸酯衍生物均采用多核(1 H、13 C、19 F、31 P 和119 Sn)NMR、IR 和紫外-可见光谱技术进行表征。使用循环伏安法 (CV) 研究了这些化合物的电化学行为;结果表明,氟代烷基呈现反向单电子转移的氧化反应更加困难(ΔE 1/2 相比,非氟化烷基(如ΔE=
