SYNTHFESIS,STRUCTURE AND RFACTION OF TETRAMETHYL-DISILANDIYL DICYCLOPENTADIENYL TETRACARBONYL DI-IRON

摘要

The title compounds（Me2SiSiMe2）（η-RC3H3）Fe（CO）（μ-CO）2（R:H（1a）,Me（1b））wereprepared by heating a solution of RC?H4（Me2SiSiMe2）C5H4R and Fe（CO）5 in xylene atreflux.（1a）and（1b）can convert into their isomers Me2Si（η-RC3H3）Fe（CO）2（?）2（R:H（2a）,Me（2b））under the reaction conditions.The crystal and molecular structures of（1a）,（2a）and（2b）were determined by X-ray diffraction.
