Bis(pentachlorophenyl)acetic acid esters were synthesized from the α-hydroxydiaryl acetate esters 13 via the free radicals 15 formed on homolytic cleavage of the α-chloro compounds 14.The acid 8 underwent rapid decarboxylation in basic solution (e.g., Et3
Regiospecificity in the Alkylation of Ester Enolates: Synthesis of Sterically Hindered Diarylketene Acetals

The alkylation of the enolates of methyl bis(pentamethylphenyl)acetate and of isopropyl bis(pentachlorophenyl)acetate occurs exclusively on oxygen to yield the diarylketene acetals; the extreme steric hindrance of these groups is also responsible for the stability of these ketene acetals in acid.
