Graphical Abstract
Square goes to loop: A selective synthesis of [8]cycloparaphenylene under mild and neutral reaction conditions was achieved in a small number of steps and in a high yield through the square-shaped platinum biphenyl intermediate 1. Compound 1 is the smallest cycloparaphenylene derivative synthesized to date.
