二苯基硫脲的配位取代反应及其红外光谱表征

Substitution of Diphenyl Sulfurine to Trinuclear Clusters and Infrared Spectra Characterization

研究了二苯基硫脲分别与十二羰基三钌和十二羰基二铁的配位取代反应。红外光谱跟踪反应从开始到结束。谱图数据揭示出原始物消失和新物质的形成过程。并对产物Ru3 (CO) 9CSN2 HPh2 和Fe3(CO) 8S2 CNPh作了KBr压片红外光谱表征。

Substitution of diphenyl sulfurine to dodecarbonyl triruthenium and dodecarbonyl triiron were studied respectively.Infrared spectra were used in characterization of the reactions and to follow the reaction processes from starting to finishing.Spectra data showed that the new compounds appeared and starting materials disappeared.The results products Ru 3(CO) 9CSN 2HPh 2 and Fe 3(CO) 8S 2CNPh were taken in KBr pellet infrared spectras.C,S and N in diphenyl sulfurine might coordinate to transitionmetal atoms in the clusters.Since trinuclear ruthenium and iron clusters have different stability and diphenyl sulfurine induced attacked to cluster skeleton in reaction,Ru 3(CO) 12 and Fe 3(CO) 12 give different corrdination structure trinuclear Ru and Fe clusters,in which every metal atom forms 18 e constitution.
