CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishCompounds of general formula Mo(g6-arene)(CO)3, arene¼diphenyl, 1; 1,3,5-triphenylbenzene, 2; C6H5F, 3; C6H5CF3, 4, have been prepared in good yields by reacting fac-Mo(CO)3(DMF)3, DMF¼N;N-dimethylformamide, with BF3 OEt2 and the appropriate arene. The crystal and molecular structures of 1, 3, and 4, are reported. The dinuclear derivative Mo2(g6:g6-C6H5- C6H5)(CO)6, 5, was obtained by thermal reaction of Mo(g6-toluene)(CO)3 with Mo(g6-diphenyl)(CO)3. An electrochemical study has been performed on the new complexes, showing that the dimolybdenum complex undergoes a single two-electron reduction at about the same potential as the corresponding dichromium complex, the molybdenum dianion being less stable than the chromium analogue.
