49_04b/2010Inside Cover: Synthesis of [8]Cycloparaphenylene from a Square-Shaped Tetranuclear Platinum Complex (Angew. Chem. Int. Ed. 4/2010)

From a square to a loop! In their Communication on page 757 ff., S. Yamago et al. describe the first synthesis of [8]cycloparaphenylene, which was achieved in three steps in 25 % overall yield from 4,4'-bis(trimethylstannyl)biphenyl and [PtCl2(cod)] (cod=1,5-cyclooctadiene) through a square-shaped platinum biphenyl intermediate. [8]cycloparaphenylene shows strong yellow-green fluorescence around 540 nm.
