Synthesis of Metal Complexes with Bis(phenalenyl)imine Ligands Synthesis 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 .
