The currently accepted name for (1) in Chemical Abstracts is dibenzothiophene, although biphenylene, diphenylene, or biphenylylene sulfide are still used, especially in the Russian literature. Occasionally 9-thia-fluorene is used and recently, in one instance, dibenzo[6,d]thiophene. An alternative numbering system for (1) is met with on occasions in which C-4 is taken as C-1, as in carbazole. In the absenee of moleeular diagrams this system must be detected by reference to the chemistry described. For example, in a few dyestuff patents 2,7-diaminodibenzothiophene 5,5-dioxide is referred to and this is obviously the 3,7-diamino compound, also known as benzidine sulfone. 

Thianthrene is numbered as shown in 1 using current Chemical Abstracts numbering before 1937, the numbering shown in 2 was used in Chemical Abstracts. The ring positions ortho to sulfur have been termed a, and the others are termed y3. Alternative names for thianthrene, found more in older literature, are dibenzo-1,4-dithiadiene, dibenzo-1,4-dithiin, di-o-phenylene sulfide, and diphenylene disulfide. The literature also contains references to o-thianthrene this is dibenzo[c,e][l,2]dithiin, (3).
