'Nindigo': A New Ligand Architecture
By applying standard carbonyl-to-imine conversion chemistry to the famous dye molecule indigo, a team of chemists led by Robin G. Hicks of the University of Victoria, in British Columbia, has created a ligand with two β-diketimine metal-binding sites fused together in a bridging architecture (Chem. Commun. 2010, 46, 6753). The diketimine structural motif in which a pair of nitrogen atoms binds a metal is popular for its easy construction and for its tunability . . .
