Succinic anhydride → Irgacure 2959 monosuccinate

Participants

Reaction Steps

As an illustrative example, a tri-functional compound can be prepared as follows. Irgacure 2959 (4-(2-hydroxyethoxy)phenyl-(2-hydroxy-2-propyl)ketone) can be reacted with succinic anhydride (reflux in triethylamine/Toluene) to obtain Irgacure 2959-monosuccinate. Norbloc (2-{3-(2H-Benxotriazol-2-yl)-4-hydroxyphenyl}ethyl methacrylate) is reacted with the obtained Irgacure 2959-monosuccinate in the presence of N,N-dicyclohexyl carbodiimide (DCC) and 4-(dimethylamino)pyridine (D-MAP) to obtain conjugated Irgacure 2959-Norbloc.
