Cycloparaphenylene (CPP) was selectively synthesized in four steps in 13% overall yield from commercially available 4,4′-diiodobiphenyl by using mono-I–Sn exchange, Sn–Pt transmetalation, I–Pd exchange, and subsequent oxidative coupling reactions. The single-crystal X-ray structure of CPP is described.
