Sulfur Compounds in Crude Oil, II - 6,11-Dihydrodiindenothiophenes

Ring closures with 3,5-diphenyl-2,4-thiophenedicarboxylic acid and theirderivates 2 have been studied.Ring closure to the indenothiophene system 3 occurs with identical functional groups in the 2- and 4-position at the thiophene ring.The indenothiophene system 4 is the reaction product from methyl 5-chloroformyl-2,4-diphenyl-3-thiophenecarboxylate with the more reactive functional group in the 5-position at the thiophene ring.The indenothiophene 4b is the starting material for 6,11-dihydrodiindenothiophenes 5.The with truxenecontaminated parent compound 5 is also obtained from 3,5-diphenyl-2,4-thiophenedimethanol (2f) with polyphosphoric acid.
