Talk:Dibenzothiophene

Preparation not supported by citation
The claim that dibenzothiophen can be produced from biphenyl, sulfurd dichloride and aluminium chloride is not supported by the cited literature. The paper prepares Dibenzothiophene from Biphenyl, sulfur, methanol etc. on alumina (Al2O3) catalysts. At least if i read everything correct. 141.244.113.42 (talk) 18:50, 7 May 2023 (UTC)
