| Hazard Information | Back Directory | [Uses]
2,2''-Bis(2-chlorophenyl)-4,4'',5,5''-tetraphenyl-1,2''-biimidazole (CAS# 7189-82-4) is a hexaarylbiimidazole (HABI), a visible light thiol-ene photoinitiator, such as in the polymerization of 1,6-hexanediol diacrylate by hexaarylbisimidazoles and heterocyclic mercapto compounds. | [Synthesis]
Preparation of a bisimidazole photoinitiator (BCIM):
1. BCIM monomer wet cake is oxidatively coupled using H₂O₂ in a biphasic system (aqueous alkali/dichloromethane) with a quaternary ammonium salt as phase-transfer catalyst.
2. Work-up: separation |
