This paper describes the preliminary study on the mechanism andkinetics of isomerization of safrole and eugenol catalyzed by iron carbonyls. A possible mechanism for this reaction is as follows: Some coordinately unsalurated iron carbonyls are formed from iron carbon-yls by irradiation or heating,then they combine with some alkene(i.e.safroleor eugenol),forming coordinately unsaturated iron carbouylsalkene complex.The alkene in this complex is isomerized and the transformed alkene is substi-tuted by another...

This paper describes the preliminary study on the mechanism andkinetics of isomerization of safrole and eugenol catalyzed by iron carbonyls. A possible mechanism for this reaction is as follows: Some coordinately unsalurated iron carbonyls are formed from iron carbon-yls by irradiation or heating,then they combine with some alkene(i.e.safroleor eugenol),forming coordinately unsaturated iron carbouylsalkene complex.The alkene in this complex is isomerized and the transformed alkene is substi-tuted by another alkene molecule surrounding the complex,thus the formerchanges into its isomer,the final product.This model of mechanism conformsto the first order kinetics of isomerization of safrole or eugenol photocatalyzedby pentacarbonyl iron.

本文对羰基铁催化黄樟油素、丁香酚异构化反应的机理及动力学进行了初步的研究,提出以下可能的反应机制:羰基铁在光照或加热下,首先形成配位不饱和羰基铁;随后,配位不饱和羰基铁与烯烃(如黄樟油素、丁香酚)生成络合物;络合物中的烯烃因电子离域作用而异构化;环境中的烯烃再取代络合物中的异构化烯烃,从而产生异构烯烃。此机制模型与五羰基铁光催化黄樟油素、丁香酚异构化反应的一级动力学一致。
