(2-alkylthiobenzoyl)ferrocenes has been achieved by Friedel–Crafts acylation of ferrocene with acid chlorides generated in situ from the corresponding carboxylic acids and phosphorous trichloride. The obtained compounds were characterized by spectroscopic data (UV, IR, 1H and 13C NMR), whereas their electrochemical properties have been investigated by cyclic voltammetry. The single-crystal X-ray structure determinations
一锅法合成了七种新的(2-烷基硫代苯甲酰基)二茂铁,这是通过将二茂铁与相应的羧酸和三氯化磷原位生成的酰氯进行Friedel-Crafts酰化反应而实现的。所得化合物通过光谱数据(UV,IR,1 H和13NMR),而其电化学性质已通过循环伏安法研究。还报告了其中三个的单晶X射线结构测定。这三种衍生物均表现出分子内C–H…O相互作用,其中涉及环戊二烯基(Cp)环的供体和羰基氧作为受体。这种相互作用有利于两个部分的共面排列。符合C–O键的向量与相应的Cp平面之间的夹角均小于6.4°。常规的氢键在这三个晶体结构中都不存在,但是已经发现并详细分析了某些类型的C–H…O,C–H…S和C–H…π类型的弱分子间相互作用。
