Isocyanato- (1a), 1,1′-di(isocyanato)- (2a), isothiocyanato- (1b), 1,1′-di(isothiocyanato)- (2b), isoselenocyanato- (1c) and 1,1′-di(isoselenocyanato)ferrocene (2c) were prepared and studied by 1H, 13C and 14N NMR spectroscopy. Isocyanatoferrocene (1a) trimerizes upon chromatography on alumina to give 3a. The molecular structures of 2c and 3a were determined by X-ray analysis, and almost undistorted
异氰酸根合- (1a), 1,1'-二(异氰酸根合)- (2a), 异硫氰酸根合- (1b), 1,1'-二(异硫氰酸根合)- (2b), 异硒氰酸根合- (1c) 和 1,1' -二(异硒氰酸根合)二茂铁(2c)被制备并通过1H、13C和14N NMR光谱学进行研究。异氰酸二茂铁 (1a) 在氧化铝色谱上三聚,得到 3a。通过X射线分析确定了2c和3a的分子结构,在两种情况下都发现了几乎未变形的类二茂铁结构。
