摘要：

By use of one particular enantiomer of the ligand N-(α-phenylethyl)dithiocarbamate (pedtc) the cobalt complexes [Co(pedtc)3] have been prepared in optically active forms. The system shows marked stereoselectivity during synthesis and it has been found that with the (-) ligand, A-[Co-(-)-(pedtc)3] can be isolated in pure form while the (+) ligand yields A-[Co-(+)-(pedtc)3]. In nonpolar or weakly polar solvents the configuration of the complex has been found to undergo inversion to the opposite chirality, thus yielding a diastereoisomer which can be isolated in pure form. Reasons for the stereochemical preferences and changes are discussed and related to other systems. © 1979, American Chemical Society. All rights reserved.
