A stable π-expanded o-quinodimethane derivative (2) was synthesized by photochemical dearomative cycloaddition of corannulene with an isolable dialkylsilylene (1) and isolated as a dark blue solid. Compound 2 adopts very flat bowl shape in contrast to parent corannulene. Structural spectroscopic characteristics, redox properties, computational study suggest that has small but significant diradical character (y0 = 0.11). One-electron reduction provides the corresponding radical anion salt.
