Bromination of phenanthrene

Phenanthrene-9-carbonitrile, prepared by bromination of phenanthrene to the 9-bromo derivative54 and its transformation by cuprous cyanide in dimethylform-amidess, served as starting material for the needed phenanthrene-9-acetonitrile (86). By the same sequence of steps as when converting phenanthrene- 1-carbonitrile (72a) to (81) the 9-carbonitrile was converted to (86), giving an overall yield of 60%. The standard procedure leads very smoothly to the triphenylenes (57) ... [Pg.165]
