The main objective of this study is the synthesis of 2-formyl rubrene (5,6,11,12-tetraphenyltetracene-2-carbaldehyde). A smooth and efficient method for the formylation of 2-(dibromomethyl)-6,11-diphenyltetracene-5,12-dione is described using N,N-dimethylformamide or N,N-dimethylacetamide as both the formylating agent and solvent, without any additional base. The product, 5,12-dioxo-6,11-diphenyl-5,12-dihydrotetracene-2-carbaldehyde is obtained in quantitative yield and is converted into the target compound via three additional steps.
