Lv. Manuilova et al., OXIDATIVE HYDROGENATION OF TETRAHYDROTHIOPHENE TO THIOPHENE ON METAL SULFIDES, Reaction kinetics and catalysis letters, 54(2), 1995, pp. 293-295
Dehydration tetrahydrothiophane the presence of air oxygen over MoS2 a
t 365-380 degrees C may produce thiophene in a yield of 77% and select
ivity of 90-100% without benzene admixtures.
