- W2028453478 abstract "L'agrandissement stéréospécifique du cycle aromatique des complexes (Arene)Cr(CO)3 avec PhCH2Cl et LiN(iPr)2 conduit aux complexes (7-phényl cycloheptatriène-1,3,5)Cr(CO)3. La position endo du groupe phényl dans ces composés a été confirmée par une étude de diffraction RX sur le dérivé 3-éthyl 7-endo phényl cyloheptatriéne-1,3,5 chrome tricarbonyle. Une extension de cette réaction avec deux autres dérivés halogénés, e.g. (PH)2;CHCl ou CH2CHCH2Br, est aussi présentée et une approche du mécanisme discutée. Stereospeciflc ring expansions of (Arene)Cr(CO)3 complexes with PhCH2Cl and LiN(iPr)2 gave (cyclo-heptatriene)Cr(CO)3 complexes whose endo structures have been confirmed by an X-ray diffraction study on the 3-ethyl endo 7-phenyl cyclohepta-1,3,5-triene tricarbonyl chromium complex. Extension of the reaction to (Ph)2CHCl or CH2CH-CH2Cl is reported. A possible mechanism is discussed." @default.
