Reduction of ferrocenylketoximes by titaniumtrichloride provides a convenient route for the preparation of ferrocenyliminium salts, which have been shown to be useful for the synthesis of new derivatives.

Abstract Triorganoantimony(V) complex (C5H5FeC5H4C(CH3) NO)2SbPh3 (1) has been prepared by the reaction of Ph3SbCl2 with acetylferroceneoxime C5H5FeC5H4C(CH3) NOH (2) in 1:2 molar ratio in anhydrous toluene. The complexes have been characterized by elemental analyses, IR and NMR (1H and 13C) spectroscopic studies, and biologic activity was measured. And crystal structures of 1, 2 were reported.

of the linear free-energy relationships (LFER) and the Marcus formalism for an outer-sphere electron transfer. There is a linear correlation with a negative slope between ln k3 and the formal redox potentials of ferrocenes (E°′) for the mono- and di-substituted molecules suggesting that, in this series, k3 increases with increasing the reaction driving force. The pentamethylated derivatives Cp*FeC5H4X
稳态辣根过氧化物酶(HRP,同工酶C)催化过氧化氢将各种单,二(1,1')和五甲基二茂铁氧化为相应的二阶速率常数(k 3) 25°C,pH 7的三价铁阳离子已用于研究线性和自由电子关系(LFER)和外层电子转移的Marcus形式论对反应性的空间和电子效应。对于单和双取代分子,ln k 3与二茂铁的形式氧化还原电势(E °')之间具有负斜率线性相关, 这表明在此系列中,k 3随着反作用力的增加而增加。五氟甲基化衍生物Cp * FeC 5 H 4 X的E °'值与其他二茂铁相比显着更低,如基于LFER所预期的,其反应活性显着降低。假设Cp * FeC 5 H 4 X的驱动力的大幅增加被五甲基化的环戊二烯基环所施加的位阻滞后所抵消,则可以使这种观察合理化。据信,从C 5 H 4 YFeC 5 H 4发生的空间位阻会增加从有机金属供体到HRP血红素的电子转移距离。X至Cp * FeC 5 H 4

cyclopentadiényl(s) drastically change the nature of ligand exchange reactions of ferrocenes. The reactivity of ketone, aldehyde, alcohol, acid, ester and oxime groups has been examined; simple and double ligand exchange is shown to occur together with transformations of the functionnal groups, providing a route to newpolynuclear cations.
