New, non-pyrolytic methods are presented for the synthesis of curved-surface, polynuclear aromatic hydrocarbons related to the fullerenes. Tetrabromocorannulene is conveniently prepared on a large scale and then converted to corannulene, and also use

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 furth

The question of an anion within an anion structure for corannulane tetraanion is examined by ab initio and semi-empirical calculations, as well as by the behavior of corannulene anionic intermediates in anhydrous ammonia. Calculations do not lend muc

The authors have provided an improved synthesis of 1,2,5,6-tetraketopyracene (6), in that three steps have been replaced with one high-yield step. Moreover, a very unreliable step has been eliminated. In turn, this has led to an improved synthesis of

The reduction of aromatic compounds by alkali metals in liquid ammonia represents an important method for the preparation of partially unsaturated six-membered rings. The reaction was discovered by Wooster and Godfrey, but the major development resul
