Potassium Iodide → 4-Bromo-4'-decyloxybiphenyl

참여 물질

반응 단계

Quantities: 4-bromo-4′-hydroxybiphenyl (67) (20.00 g, 0.08 mol), 1-bromodecane (22.12 g, 0.10 mol), anhydrous potassium carbonate (57.10 g, 0.413 mol), potassium iodide (trace), butanone (500 ml). The experimental procedure was as described for the preparation of compound 57. The cooled mixture of product and inorganic salts was filtered off and washed carefully with dilute hydrochloric acid to remove the potassium carbonate. The white product was then washed with water until acid-free and heated under reflux with a minimum volume of ethanol to remove traces of 1-bromodecane. The product was filtered off, washed with cold ethanol and dried in vacuo to yield colourless crystals.
