SYNTHESIS OF STERICALLY ENCUMBERED 2,9-DIARYL SUBSTITUTED PHENANTHROLINES - KEY BUILDING-BLOCKS FOR THE PREPARATION OF MIXED (BIS-HETEROLEPTIC) PHENANTHROLINE COPPER(I) COMPLEXES (I)
M. Schmittel et al., SYNTHESIS OF STERICALLY ENCUMBERED 2,9-DIARYL SUBSTITUTED PHENANTHROLINES - KEY BUILDING-BLOCKS FOR THE PREPARATION OF MIXED (BIS-HETEROLEPTIC) PHENANTHROLINE COPPER(I) COMPLEXES (I), Heterocyclic communications, 3(6), 1997, pp. 493-498
The preparation of several novel 2,9-diaryl phenanthrolines is describ
ed. Depending on the steric shielding the formation of bis-homoleptic
phenanthroline copper(I) complexes can be suppressed and mixed phenant
hroline complexes can be prepared.
