Abstract

1343445 Dimerizing styrenes BADISCHE ANILIN- & SODA-FABRIK AG 11 June 1971 [12 June 1970] 27416/71 Heading C5E 1-Alkyl-3-phenyl indans are prepared by catalytically dimerizing a styrene optionally containing alkyl substitutents in the presence of a polymerization inhibitor. Suitable catalysts are phosphoric, sulphuric or haloalkanoic acids or a silica-containing material. The reaction may be carried out at 30-200‹ C. optionally in an organic solvent. Examples describe the preparation of 1-methyl-3-phenyl indan by dimerizing styrene in the presence of a wide variety of polymerization inhibitors which include thioureas, phenols, thiophenols and ethers thereof, sulphur-containing heterocyclic compounds, aromatic amines, nitroso compounds, organophosphorus -compounds, thiocarboxamides, disulphides, nitro compounds, quinones, and polyamides, in amounts 10<SP>-5</SP> to 10<SP>-2</SP> moles per mole styrene.
