“…Only few infrared spectra or parts of spectra of Grignard reagents are depicted or described in literature. ,,,− ,, Most of these spectra were obtained from the Grignard reagent in THF or DEE. In addition, several Grignard reagents are mentioned in the literature to be analyzed or identified by infrared spectroscopy, but the spectra were not reported, ,,,, including benzylmagnesium chloride, 5-fluoro-2-methoxyphenylmagnesium bromide, methylmagnesium iodide, 2-thienylmagnesium bromide and vinylmagnesium bromide . In other publications, infrared spectroscopy has been used to follow the formation of Grignard reagents or the Grignard reaction.…”
