4,4'-Dihydroxybiphenyl → 4,4'-Bis-(4-dimethylsilylbenzoyloxy)biphenyl

Participants

Reaction Steps

A solution of 49.7 g (0.250 mol) of p-dimethylsilylbenzoyl chloride and 18.6 g (0.100 mol) of 4,4'-dihydroxybiphenyl in 40 ml of dry dioxane was boiled for 15 hours. The completeness of the reaction was checked by thin-layer chromatography. After the solvent had been stripped off in vacuo on a rotary evaporator, the crude product was recrystallized from toluene, to give 4,4'-bis-(4-dimethylsilylbenzoyloxy)biphenyl, [-4 s 146 n 184 i].
