Reaction Steps
Synthesis I: A solution of tetrahydroxybenzophenone (Aldrich Chemical) is treated with sufficient caustic, i.e. sodium hydroxide, to prepare a disodium phenolate salt. This salt solution is mixed at a two to one molar ratio with dichloromethylmethoxysilane (Aldrich, United Chemicals) to yield 2,2′ di-(dimethoxymethylsilyoxy), 4,4′dihydroxy-benzophenone having the structure shown in FIG. 8(a).
