✦ Synopsis

On reaction with hydrogen sulfide in strongly acidic media, difurylalkyl-(aryl)methanes are converted to furylthienylalkyl(aryl)-or dithienylalkyl-(aryl)methanes, depending on the conditions.

When furan compounds react with hydrogen sulfide or selenide under conditions of acid catalysis, they are converted into the corresponding thiophenes or selenophenes [1][2][3][4][5]. In order to further study the reaction, we have considered the recyclization of difurylalkyl-(aryl)methanes I-V: CH \CH3 R CH3/'~--0 ~ ~O/'~-CH~ '~-.. ~.
