Full title: Transition-metal-substituted diphosphenes. 29. Cycloaddition reactions of the diphosphenyl complex (η5-C5Me5) (CO)2Fe-P=P-Mes * (Mes * = 2,4,6-tBu3C6H2) with hexafluoroacetone. X-ray structure analyses of (η5-C5Me5)(CO)Fe-P(=PMes*)OC(CF 3)2C(O) and (η5-C5Me5)(CO)2Fe-P-P(Mes *)OC(CF3)2. The diphosphenyl complex (η5-C5Me5)-(CO) 2Fe-P=P-Mes* (Mes* = 2,4,6-tBu3C6H2) undergoes a [3 + 2] dipolar cycloaddition with hexafluoroacetone to give the metalla heterocycle (η5-C5Me5)(CO)-Fe-P(=PMes*)OC(CF 3)2C(O) with a remarkably short Fe-P bond (2.084 (4) A?) and an exocyclic P=P bond. When stored In solution at -40°C, this complex partly rearranges to the metalated 1-oxa-2,3-diphosphetane (η5-C5Me5)(CO) 2Fe-P-P(Mes*)OC(CF3)2. The molecular structures of both isomers were elucidated by single-crystal X-ray analyses.
