Abstract: | Isocyanoferrocene ( 1 ) and 1, 1′‐diisocyanoferrocene ( 2 ) were prepared and studied by 1H, 13C, 14N and 57Fe NMR spectroscopy in order to gain a more complete data set. The NMR data of 1 (chemical shifts and coupling constants) were calculated by DFT methods B3LYP/6‐311+G(d, p)] and compare favourably with experimental data. The molecular structure of 1 was determined by X‐ray structural analysis, and an almost undistorted ferrocene‐like geometry was found. |
