development of highlysubstituted phenanthrenyl phenyl selenides 4 and 6 by metal-catalyzed cyclization of o-phenylarylalkynes species 1 was successfully performed. The selectivity for 9- and 10-selenyl phenanthrenes was perfectly controlled by indium(III) and gold(I) catalysts, and the reactions proceed through different pathways. For the In(OTf)3 catalyst system, 6-endo cyclization of alkyne 3 gives
