Abstract

Abstract Optically active alkyl cobalt complexes, CH3CHXCo(Hdmg)2·Base [X=COOCH3 or CN; Base=(R)- or (S)-1-phenylethylamine, H2O, pyridine, or (1R,2S)-1,2-diphenyl-2-aminoethanol; Hdmg=dimethylglyoximate(1-)], have been prepared, and their spectroscopic and chiroptical data are given. The rotational contribution of the chiral alkyl moiety was shown to be considerably greater than that of the chiral amine moiety. This suggests that the rotational sign (in the longer-wave length region of about 546 to 589 nm) may be useful for deducing the chirality of the alkyl moiety.
