Abstract

267,940. I. G. Farbenindustrie Akt.- Ges. March 16, 1926, [Convention date]. Samples furnished. Indanones are obtained by treating aromatic hydrocarbons and their substitution products with a halide of a #-halogen-substituted fatty acid, converting the halogenated ketone thus obtained into an unsaturated ketone by means of an agent capable of splitting off hydrogen halide. e.g. by distillation or bv the action of sulphuric acid, and finally treating the unsaturated ketone with an acid condensing agent, e.g. aluminium chloride or sulphuric acid. The reaction may be conducted in several stages or in a single operation. In examples (1) 1-methylnaphthalene is treated with #-chlorpropionyl chloride in the presence of a suspension of aluminium chloride in carbon disulphide, the 1-methyl-4-#-chlorpropionyl-naphthalene obtained is heated with sulphuric acid and the product is poured into water; 5-methyl- 6: 7-benzo-1-indanone separates out and (2) 1- methylnaphthalene is similarly treated with #- chlorbutyryl chloride to yield 1-methyl-4-#- chlorbutyryl-naphthalene, this is distilled in a vacuum to form 1-methyl-4-crotonylnaphthalene which yields 3 : 5-dimethyl-6 : 7-benzo-1-indanone when heated with sulphuric acid. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of substitution products of halides of #-halogen-substituted fatty acids as parent materials. This subjectmatter does not appear in the Specification as accepted.
