Abstract

Abstract 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 C1-C1-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 ...
