本文进一步研究了羰基铁络合物光催化黄樟油素(1)和丁香酚(2)异构化反应的机理。催化剂Fe(CO)_4(butadiene)和Fe(CO)_3(butadiene)对1和2具有几乎相同的活化能以及动力学参数(m,n),这说明反应可能经过同一类型的过渡态。在320～610 nm间进行光异构化反应时,只要光的波长能分解催化剂,则反应就能进行,这说明反应的关键是配位不饱和羰基铁与烯烃络合物的生成。 In this paper, the mechanism of isomerization of safrole (1) and eugenol (2) catalyzed by carbonyl iron complexes was further investigated. The catalysts Fe (CO) 4 butadiene and Fe (CO) 3 have almost the same activation energy and kinetic parameters (m, n) for 1 and 2, indicating that the reaction may pass through the same type of transition state. When the photoisomerization reaction is carried out at 320-610 nm, the reaction can proceed as long as the wavelength of light can decompose the catalyst, indicating that the key reaction is the formation of complex carbonyl iron and olefin complex.
