摘要:
Replacement of one CO ligand in the enantiomeric 2-methylcymantrenecarboxylic acid ester for a radical ligand PhS results in the preparation of stable and optically active odd-electron complex CH3C5H3COOCH3Mn(CO)(2)SPh] fully characterized by electron spin resonance, mass spectroscopy, UV-visible spectroscopy, IR spectroscopy and circular dichroism spectroscopy. This is the first example of an optically active organometallic free radical.
