Treatment of 2 equiv of indole-3-aidehyde with o, m, p-xylyl, 2,5-dimethoxy-p-xylyl dibromides and 4,4'-bis(bromomethyl)-1,1'-biphenyl gave the bisalkylated products, which underwent McMurry coupling with low valent titanium to give indolophanes. Various cis-stilbenophanes with m-terphenyl building blocks were also synthesized by application of the McMurry coupling technique. (C) 2004 Elsevier Ltd. All rights reserved.
