N,N-二苯基甲酰胺和N,N-二苯基乙酰胺的合成及光谱性质
Synthesis and Spectral Properties of N,N-Diphenylformamide and N,N-Diphenylethanamide
摘要
Abstract
Using diphenylamine as the starting material,and N,N-dimethylformamide and N,N-dimethylacetamide as the acylating reagents,N,N-diphenylformamide and N,N-diphenylacetamide were synthesized via the Vilsmeier-Haack reaction.The chemical structures and spectral prop-erties of N,N-diphenylformamide and N,N-diphenylacetamide were characterized by proton nuclear magnetic resonance spectroscopy(1 H NMR),Fourier transform infrared spectroscopy(FT-IR)and ultraviolet-visible absorption spectroscopy(UV-Vis).The results showed that the acylation reaction occurred at the imino group.Compared with the maximum absorption wavelength(λmax)of diphenylamine,the λmax values of N,N-diphenylformamide and N,N-diphenylacetamide exhibited a significant blue shift.The introduction of the acyl group disrupted the conjuga-tion of diphenylamine,leading to the obvious blue shift of the λmax of the corresponding products.关键词
