Dibenzothiophene is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It is a colourless solid that is chemically somewhat similar to anthracene. This tricyclic heterocycle, and especially its alkyl substituted derivatives, occur widely in heavier fractions of petroleum.
Synthesis and reactions
Reduction with lithium results in scission of one C-S bond. S-oxidation occurs to give the sulfone, which is more labile than the parent dibenzothiophene. With butyl lithium, this heterocycle undergoes stepwise lithiation at the 4- and 6- positions.
