A method for the synthesis of previously unknown 4,6-dinitro-2-trihalogenomethyl-2,3-dihydrobenzo[b]furans has been elaborated. The method is based on condensation of 2,4,6-trinitrotoluene with fluoral or chloral in the presence of K2CO3 with subsequent intramolecular cyclization of the resulting 2-picryl-1-(trihalogenomethyl)ethanols.
