Synthesis of Metal Complexes with Bis(phenalenyl)imine LigandsSynthesis of model pigments and their metal chelates with Zn, Co, Ni, and Mn (26a-d) are described. The former are obtained from 2,4-dihydro-4,9-dihydroxy-1,2,4-phenalenethione (14b) by connecting two molecules in a ninhydrin-like reaction with nitrogen to the ligand 8. These models confirm the structure of the zinc complex 2 isolated from the ascomyces Roesleria hypogea. Isolation of the rearranged ester 18 proves this compound to be an intermediate in the mechanism of the degradation process of phenalenetriones 14 to acenaphthoquinones 16.
