Structural control of metalloporphyrinogens by macrocycle modification: steric blocking of the macrocyclic cavity through trans-N,N′-dimethylation
Abstract
Reactions of potassium metal with trans-N,N′-dimethyl-meso-octaethylporphyrinogen or meso-octaethyldioxaporphyrinogen afford dipotassium complexes with one potassium
