摘要：

The one-pot syntheses of alkyl-10,11-dihydrodiindeno[1,2-b:-2',1'-d]thiophenes (3) by bromination and sulfurization of alkylindan-1-ones without substituents at C-2 (1) has been studied with 14 1 with C1C4-rests at the benzene and or the cyclopentane ring. 9 dialkyl-3 and 3 tetraalkyl-3 are prepared in yields of 7-66%; an octamethyl-3 is detected by tlc and ms. 2 dialkyl-3 are prepared too by an independent syntheses from dimethyl 2,5-bis(methylphenyl)thiophene-3,4-dicarboxylates (13). The mechanism of the one-pot syntheses, which gives diindeno-1,4-dithiines too, is discussed. The oxidation of 4 3 has been studied.
