Synthesis,structure, and NMR spectra of a new ferrocenylbenzene tricarbonylchromium complex
Abstract:Complex 1 (1,2,4-triferrocenylbenzene tricarbonylchromium), possessing four heterometals, has been synthesized efficiently by a new method in one pot. Through detailed study on the NMR chemical shifts of 1 and the ligand 2, the NMR chemical shifts of 1 shift upfield from those of 2. The NMR spectra of 1 have reduced magnetic anisotropy of benzene after Cr(CO)3 coordination with 2. The ferrocenyl groups have electron donating effect on the central benzene ring of 1.
Keywords:Synthesis  NMR spectra  Ferrocenylbenzene tricarbonylchromium complex  Ring current
