报道了[2，3，4，5-Ph-4（eta（4）-C4 CO）]Ru（CO）（3）（5a）与Na 2CO 3在丙酮水溶液中反应，然后用NH 4Cl低温处理，得到物质A，其被配制为异丙醇配合物[2，3，4，5-Ph-4（eta（4）-C4 CO）]（CO）（2）Ru（HOCHMe 2）（3a）。对该反应的重新研究表明，A是异丙胺配合物[2，3，4，5-Ph-4（eta（4）-C_4CO）]（CO）（2）Ru（H_2NCHMe_2）（4a）. 4a的形成被认为是通过形成丙酮的亚胺，然后通过在5a与Na 2CO 3在丙酮水溶液中的反应中形成的（羟基）氢化钌[2，3，4，5-Ph-4（eta（5）-C4 COH）]Ru（CO）（2）H（2a）还原亚胺，然后用NH 4Cl水溶液酸化而发生的。
The reaction of [2,3,4,5-Ph-4(eta(4)-C4CO)]Ru(CO)(3) (5a) with Na2CO3 in aqueous acetone followed by low-temperature treatment with NH4Cl was reported to give the material A, which was formulated as the isopropyl alcohol complex [2,3,4,5-Ph-4(eta(4)-C4CO)](CO)(2)Ru(HOCHMe2) (3a). Reinvestigation of this reaction indicates that A is instead the isopropylamine complex [2,3,4,5-Ph-4(eta(4)-C4CO)](CO)(2)Ru(H2NCHMe2) (4a). The formation of 4a is proposed to occur by formation of the imine of acetone followed by reduction of the imine by the (hydroxycyclopentadienyl)ruthenium hydride [2,3,4,5-Ph-4(eta(5)-C4COH)]Ru(CO)(2)H (2a) formed in the reaction of 5a with Na2CO3 in aqueous acetone and subsequent acidification with aqueous NH4Cl.
