✦ Synopsis

Synthesis of Ethynyl-Substituted Quinquephenyls and Conversion to Extended Fused-Ring Structures. -A recently developed, organometallic coupling, electrophile-induced cyclization strategy for the preparation of p-terphenyl compounds is extended to the synthesis of the title compounds, e.g. (III), critical components for a variety of advanced technologies. An unexpected cyclization pathway furnishes the fused indenyl spiro compound (VI). -(GOLDFINGER, M.
