And the article contained the following:
Although various methods for the preparation of dibenzofurans are available, an efficient, general synthesis of dibenzofurans from benzofurans remains an unsolved problem. Herein, we provide the first benzannulation of readily prepared 2-nitrobenzofurans with alkylidene malononitriles. This methodol. enables facile assembly of a wide variety of highly functionalized dibenzofurans in moderate to excellent yields under metal-free conditions. Gram-scale synthesis and further elaborations of the product were succesfully performed, demonstrating synthetic utility of this method. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Synthetic Route of 2510-01-2
