Notes:
Various aromatic nitriles were used for the preparation of the nitrile-capped clusters Fe3(CO)9(μ3-η2-RC≡N) (2) by reaction with Fe3(CO)12 under hydrogen. Electron-rich nitriles decrease, electron-poor nitriles increase the thermal stability of clusters 2. With CN-substituted pyridines only traces of clusters 2 could be obtained. CO replacement in Fe3(CO)9(PhCN) (2a) by isonitriles also causes a lowering of the stability. Conversely, more stable products were obtained by substitution reaction with trimethyl phosphite. One PPh3 and two dppm derivatives were also obtained. The structure of Fe3(CO)8-P(OMe)3(μ3-η2-PhC=N) (5a) was determined.
