以1,1'-双(磺酸)二茂铁铵盐为原料制备了一系列1,1'-双(磺酰基)二茂铁化合物。该化合物可以很容易地转化为 1,1' 双(磺酰氯)二茂铁。通过改变化学计量和反应时间,可以合成单磺酰胺衍生物和双磺酰胺衍生物。本报告中提出的所有新化合物均已进行结构表征。双磺酰胺系统的结构类似于经过充分研究的双(酰胺)二茂铁化合物。观察到分子间氢键,通常是在相邻磺酰胺的 NH 和 SO 基团之间。然而,在双 (GABA) 衍生物中,存在分子间 NH 与 CO 氢键相互作用。由相应的铵盐合成了一系列1,1'-双(磺酰氯)二茂铁化合物,并将其转化为单磺酰胺或双磺酰胺。这些化合物表现出分子间氢键。
A series of 1,1′-bis(sulfonyl)ferrocene compounds were produced via the 1,1′-bis(sulfonate)ferrocene ammonium salt. This compound can be readily converted to 1,1′ bis(sulfonylchloride)ferrocene. Varying stoichiometry and reaction times, both mono- and bis-sulfonamide derivatives can be synthesized. All new compounds presented in this report have been structurally characterized. The structures of the bis-sulfonamide systems are similar to the well-studied bis(amide) ferrocene compounds. Intermolecular hydrogen bonding is observed, typically between NH and SO groups of neighboring sulfonamides. However in the bis(GABA) derivative, intermolecular NH to CO hydrogen bonding interactions are present. A series of 1,1′-bis(sulfonylchloride)ferrocene compounds were synthesized from the corresponding ammonium salt, and converted into either mono or bis sulfonylamides. These compounds exhibit intermolecular hydrogen bonding.
