Are there alternatives to 3,3'-(1,4-Phenylenediimino)bis(4,5,6,7-tetrachloro-1H-isoindol-1-one) (CAS: 5590-18-1) in synthesis?

There are alternative reagents and synthetic pathways that can be used in place of 3,3'-(1,4-Phenylenediimino)bis(4,5,6,7-tetrachloro-1H-isoindol-1-one) (CAS: 5590-18-1). For instance, using less toxic chlorinated derivatives or exploring green chemistry approaches like microwave-assisted synthesis or solvent-free techniques can reduce the use of this highly chlorinated compound. Analogues with reduced environmental impact are also being explored in academic and industrial research.
