2-(4-chlorophenyl)phenol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 280 g (2 mols) of powdered potassium carbonate were suspended in 2 l. of methyl ethyl ketone. 409 g (2 mols) of 4'-chloro-hydroxybiphenyl were added and the mixture was heated to the boil. Thereafter 260 g (2 mols) of α-chloropinacolone were added dropwise over the course of 1 hour and the mixture was heated under reflux for 15 hours. After cooling, the solid residue was filtered off, washed and recrystallised from ligroin. 513 g (79% of theory) of [1-(4'-(4"-chlorophenyl)-phenoxy]-3,3-dimethyl-butan-2-one of melting point 90° C. are obtained. the mixture was heated to the boil the mixture was heated under reflux for 15 hours After cooling the solid residue was filtered off washed recrystallised from ligroin

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
