Benzophenone → 4,4'-(1,3-Dioxolane-2,2-diyl)diphenol

Participants

Reaction Steps

The preparation of 2,2-diphenyl-1,3-dioxolane from benzopheone under similar conditions is reported to give over 80% yield in only 5 hours reaction time, [M. Sulzbacher et al., J. Amer. Chem. Soc., 70, 2827 (1948)]. It is readily apparent that the synthesis of the ketal of 4,4'-dihydroxybenzophenone is accomplished less advantageously than the corresponding ketal of benzophenone.
