Synthesis of Dibenzo-sulfur-heterocycles through Reaction of Diphenyl-type Compounds with Elemental Sulfur over USY Zeolite

摘要

: A series of dibenzo-sulfur-heterocycle compounds , such as phenothiazine , phenoxthine, thianthrene , thioxanthene and derivatives of dibenzothiophene were synthesized with satisfactory yields through reaction of the corresponding diphenyl-type compounds with elemental sulfur over a USY zeolite
