The reaction between Cr(CO)5[C6H6] and ethyl diazoacetate (EDA) has been studied using the technique of laser flash photolysis. Results indicate that the Cr(CO)5 fragment reacts very rapidly with the EDA ligand. Low temperature spectroscopic studies suggest that in the case of W(CO)5, and by analogy also in the case of Cr(CO)5, the initial adduct between the pentacarbonyl fragment and EDA is one where
Cr(CO)5 [C 6 H 6 ]与重氮乙酸乙酯(EDA)之间的反应已使用激光闪光光解技术进行了研究。结果表明,Cr(CO)5片段与EDA配体反应非常快。低温光谱研究表明,在W(CO)5的情况下,并且类似地在Cr(CO)5的情况下,五羰基片段与EDA之间的初始加合物是重氮羰基配体的氧原子为绑定到金属中心。然后将该动力学产物转化为热力学上有利的配合物,其暂定为氮结合的W(CO)5 -EDA配合物,该配合物在室温下似乎稳定。
