Abstract
1415508 Diarene chromium compounds ALBRIGHT & WILSON Ltd 24 July 1973 [24 July 1972] 34551/72 Heading C2J [Also in Divisions B1 and C7] Diarene chromium compounds are prepared by condensing gaseous chromium atoms with an aromatic compound of formula or or a mixture thereof, at a pressure of less than 10<SP>-2</SP> torr and at a temperature compatible with maintaining said pressure, where Ar<SP>1</SP> is an alkylbenzene compound and Ar<SP>11</SP> is an unsubstituted or alkyl-substituted diphenyl, tetralin or indane compound. The process can be effected by (a) a co-condensation route by passing gaseous chromium atoms and vapour of the aromatic compound on to the surface of a reactor chilled to at least - 60 C. or (b) a liquid phase route by condensing gaseous chromium atoms in a reactor on to a continually regenerated (i.e. stirred or flowing) liquid comprising the aromatic compound and, optionally, a solvent. In the examples, bis-m-diisopropyl benzene chromium, bis-cumene-chromium, and diphenyl-, cumene-, and t-butyl-(mdi-isopropyl)benzene chromium are prepared. The compounds of the types Ar<SP>1</SP>CrAr<SP>1</SP>, Ar<SP>1</SP>CrAr<SP>11</SP> and Ar<SP>11</SP>CrAr<SP>11</SP>, other than the bis- (ethylbenzene)and bis-(diphenyl) compounds, are claimed per se but in the absence of any rearrangement or disproportionation products thereof.
