allowing the preparation of the corresponding Grignard reagents in good yields. Furthermore, the use of a cocktail of metallic salts (Mg, ZnCl2, LiCl) in the presence of C60 fullerene (3 mol %) allows preparation of some functionalized polyaromatic zinc reagents. The resulting organomagnesium and organozincreagents efficiently underwent reactions with electrophiles, such as an aldehyde, an acid chloride

A series of aromatichydrocarbons were investigated so as to compare the reactivity of corannulene with planar aromatichydrocarbons. Corannulene was found to be more reactive than benzene, naphthalene and triphenylene to Friedel–Crafts acylation whilst electrophilicaromatic bromination was also used to confirm that triphenylene was less reactive than corannulene and that pyrene, perylene and acenaphthene
