Potassium Iodide → [1,1'-Biphenyl]-4-carbonitrile, 4'-(decyloxy)-

Participants

Reaction Steps

A mixture of 4-cyano-4'-hydroxybiphenyl (56) (10.10 g, 0.052 mol), 1-bromodecane (14.38 g, 0.065 mol), anhydrous potassium carbonate (37.32 g, 0.27 mol), butanone (300 ml) and a trace of potassium iodide was heated under reflux overnight. The cooled solution was filtered to remove inorganic salts and the solvent was removed in vacuo. The residual oil was distilled (to remove excess bromide) and finally purified by column chromatography (dichloromethane) to yield a colourless, low melting solid.
