“…Of the three ancillary ligands examined, pentane-2,4-dione (acac), 1,1,1,5,5,5-hexafluoropentane-2,4-dione, and 2,2,6,6-tetramethyl-3,5-heptanedione (dpm), pure heteroleptic complexes were successfully isolated only using the dpm ligand. As seen for other heteroleptic Zn complexes, 43 , 56 zDIP2′ and zDIP3′ disproportionate to their respective homoleptic complexes (zDIP2 and zDIP3) in chloroform over the course of several hours, as observed by NMR measurements (see SI ). However, zDIP2′ and zDIP3′ are stable in the solid state and can be sublimed under vacuum without disproportionation.…”
