✦ Synopsis
Tris-{1-I-menthyloxy3-(2-naphthoyl)acetonato}-M(II1) complexes (M = Co, Cr, Mn) were synthesized and the stereoselectivities of the complexes were examined.
The complexes exhibit intense circular dichroisms in the d-d band region, demonstrating the stereoselective formation of one of the enantiomers. The preferred configuration is shown to be c&A in all the complexes. High stereoselectivities in the present complexes compared with those in tris( l-1-menthyloxy3-benzoylacetonato)M(III) complexes are discussed in terms of the intramolecular interligand CH/n-interaction occurring between the aromatic and the I-menthyl residues.
