The constitutional isomeric osmabicyclo[3.2.2]nonanes 2a and 4a are obtained by reaction of the bistriflates X(CH2OSO2CF3)2 (X = cis-1,4-(1) and cis-1,3-cyclohexane (3)) with Na2[Os(CO)4] in dimethyl ether. The analogous very unstable iron compounds 2b and 4b are obtained by the same way. In the presence of CO, the ketones bicyclo[3.2.2]nonane-3-one (5) and bicyclo[3.3.1]nonane-3-one (6) are formed
组成异构的osmabicyclocyclo [3.2.2]壬烷2a和4a是通过双三氟甲磺酸X(CH 2 OSO 2 CF 3)2(X =顺式-1,4-(1)和顺式-1,3-环己烷反应制得的(3))与在二甲醚中的Na 2 [Os(CO)4 ]。用同样的方法得到类似的非常不稳定的铁化合物2b和4b。在CO的存在下,由2b形成酮双环[3.2.2]壬烷-3-一(5)和双环[3.3.1]壬烷-3-酮(6)。和4b通过还原消除Fe(CO)5。的反应1和3与[的Re(CO)5 ] -(THF)和[锰(CO)5 ] - (二甲醚)分别得到的烃桥连络合物的顺式-1,4-(CH 2 M(CO )5)2 C 6 H 10(M = Re(2c),Mn(2d))和顺-1,3-(CH 2 M(CO)5)2 C 6 H 10(M = Re(4c),Mn(4d))。根据X射线结构分析,4c在Z = 2的三斜空间群P中结晶。
