located over the central five-membered ring of the corannulene core adding to the rare examples of a multiple metalcoordination to the inner surface of buckybowls. Upon coordination, the planar [Hg3] unit and the bowl-shaped polyaromatichydrocarbons attempt to match the geometric characteristics of each other. Thus, bending of the planar surface of [Hg3] ranging from 6.6° in 1 to 17.0° in 2 and flattening

The corannulene complex [Cp*Ru(η6-C20H10)]+ (3+; where Cp* = η5-C5Me5), prepared by the reaction of [Cp*Ru(μ3-Cl)]4 with Ag+ and the curved-surface buckybowl C20H10 (1), has a structure in which the bowl is slightly flattened as compared with the case for free corannulene. The corannuleneunit in [(Cp*Ru)2(μ2-η6:η6-C20H10)][PF6]2 (4[PF6]2), containing two η6-Cp*Ru}+ units coordinated on opposite sides

Synthesis of a number of substituted corannulenes and dibenzo[a,g]corannulenes starting from 1,2,5,6-tetrabromocorannulene 3 is described. Since 3 is conveniently obtained by a large scale, non-pyrolytic route, it may serve as a synthon for the further elaboration of this bowl-shaped system. (C) 2000 Elsevier Science Ltd.

Corannulene (C20H10, 1), a curved-surface fragment of buckminsterfullerene (C-60), forms an eta(6)-coordinated complex with Cp*Ir2+. The analogous 1,2,5,6-tetramethylcorannulene (2) complex, Cp*Ir(eta(6)-2)(2+), initially forms three isomers, but migration of the Cp*Ir2+ unit from a nonmethylated to a methylated ring gives two isomers in the final product.
