2-Hydroxybenzophenone UV-absorber containing 4,4,5,5-tetramethylimidazolidine fragment

摘要

2-Hydroxy-4-[(2,4,4,5,5-pentamethylimidazolidin-2-yl)methoxy]benzophenone (4)-2-hydroxybenzophenone UV-absorber con- taining 4,4,5,5-tetramethylimidazolidine fragment was obtained in the reaction of 4-(2-oxopropoxy)-2-hydroxybenzophenone (3) with 2,3-diamino-2,3-dimethylbutane (2).
