Significance

The authors performed an extensive screening of Lewis acid catalysts in their attempts to synthesize the polyaromatic hydrocarbons shown in this paper. While other catalysts, notably Sc(OTf)3 and [ReBr(CO)3(thf)]2, showed similar activity, In(OTf)3 displayed the greatest propensity for performing the desired transformations under the least harsh conditions. The catalyst was shown to be particularly robust: it operated well both in the presence of amines and in solvents which have not been dried or degassed.
