摘要：

In the reaction between tetrafluorodisilacyclobutene (1) and [(eta-5-C5H5)Fe(CO)2]2, a metal-mediated intramolecular fluorine migration results in an Fe-silylene intermediate that rapidly dimerizes to a disiladiferracyclic compound (6). The structure of 6 is determined by spectroscopies in solution and X-ray diffraction of a single crystal. The Fe-silylene intermediate can be stabilized (in the form of 7) by weak donor solvents such as tetrahydrofuran (THF), acetonitrile, and hexamethylphosphoric triamide (HMPT).
