1-二茂铁基-3-芳基-2-丙烯酮紫外光谱的取代基和溶剂效应

Substituent Effect and Solvent Effect on the UV Spectra of 1-ferrocene-3-ary1-2-propenone

测定了 6个 1-二茂铁基 - 3-芳基 - 2 -丙烯酮在 11种有机溶剂中的紫外光谱 ,其紫外光谱的最大吸收峰频率νuvmax与哈密特亲电取代基常数σ+ p 之间呈良好的线性关系 ,与溶剂的极性参数XR 之间也呈较好的线性关系 .

The UV spectra of six 1-fecerente-3-aryl-2-propenones in eleven solvents have been measured.The maxim frequences ν uv max linearly correlate excellently with Hammett's substituent coefficients and Brooker's solvent polar values.
