Mauthner, Nandor et al. published their research in Journal fuer Praktische Chemie (Leipzig) in 1942 | CAS: 1634-34-0

2′,6′-Dihydroxy-4′-methylacetophenone (cas: 1634-34-0) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.COA of Formula: C9H10O3

Migration of acyl groups in the orcinol series was written by Mauthner, Nandor. And the article was included in Journal fuer Praktische Chemie (Leipzig) in 1942.COA of Formula: C9H10O3 This article mentions the following:

1,3,5-C6H3Me(OAc)2 and AlCl3PhNO2 at room temperature yield (mainly) 1,3-diketo-2,4-diacetyl-5-methyl-1,2,3,4-tetrahydrobenzene, m. 93-4° (mono-p-nitrophenylhydrazone, m. 225-6°), a little 3,5,1,4-(HO)2C6H2MeCOMe (p-nitrophenylhydrazone, m. 257-8°), and a substance, m. 55-6°, b12 163-4° (no reaction with p-NO2C6H4NHNH2). In the experiment, the researchers used many compounds, for example, 2′,6′-Dihydroxy-4′-methylacetophenone (cas: 1634-34-0COA of Formula: C9H10O3).
