2,3-Homotroponeiron tricarbonyl, 8-methyl- and 8,8-dimethyl-2,3-homotroponeiron tricarbonylcomplexes have been shown to undergo O-protonation in trifluoroacetic (TFA) and 96% sulfuric acids. In the latter acid the O-protonated cations rearrange to give the thermodynamically more stable C-protonated isomers. Cyclooctatrienoneiron tricarbonyl undergoes protonation H2SO4 to give the same cation as was
已经显示出2,3-高纯铁三羰基,8-甲基和8,8-二甲基-2,3-高纯铁三羰基配合物在三氟乙酸(TFA)和96%的硫酸中经历了O质子化反应。在后者的酸中,O-质子化的阳离子重排以产生热力学上更稳定的C-质子化的异构体。环八碳三烯酮铁三羰基经过质子化H 2 SO 4,得到的阳离子与H 2 SO 4中高苯并铁三羰基络合物的质子化所得到的阳离子相同。根据在D 2 SO 4中的反应,这表明环辛三烯酮络合物的质子动力学首选位在C(2)配位碳原子之一。
