摘要
本文由反式巴豆酰氯与活性中间物[(μ=CO)(μ-R^1S)Fe_2(CO)_6]-Et_3N^+H反应,合成了两个新的μ-酰基铁硫配合物(μ-R^1S)(μ-CH_3CH=CHC0)Fe_2(CO)_6(R^1=Et,Bu^t)和三个新的μ-烯基铁硫配合物(μ-R^1S)(μ-CH_3CH=CH)Fe_2(CO)_6(R^1=Et,Bu^t,CH_2=CHCH_2)。此外还研究了μ-酰基配合物脱羰生成μ-烯基配合物的反应动力学,证明为一级反应,并求得在一定条件下的速率常数和半衰期。
Two new μ-acyl Fe—S complexes (μ-R^1S)(μ-CH_3CH=CHCO)Fe_2 (CO)_6 (R^1=Et, Bu^t) and three new μ-alkenyl complexes (μ-R^1S) (μ-CH_3CH=CH) Fe_2 (CO)_6 (R^1=Et, Bu^t, CH_2=CHCH_2) have been synthe sized by reaction of trans-crotonyl chloride with active intermediates [(μ-CO) (μ-R^1S) Fe_2 (CO)_6]-Et_3N^+H.The kinetics for CO extrusion reaction of μ-acyl complexes to form μ-alkenyl complexes has been investigated and showed that this type of reaction is first-order. The rate constants and half-life of the reactants have been calculated.
