Process for preparing 1-indanones

The present invention relates to a process for preparing 1-indanones of formula I: and isomers thereof, wherein R1, R2, R3, R4, R5, and R6 independently represent H or a C1-C20 hydrocarbon group or R1 and R2 or R2 and R3 or R3 and R4 and/or R5 and R6 together with the carbon atoms to which they are attached form a saturated or unsaturated 5- or 6-membered ring, said hydrocarbon group and/or said ring optionally containing one or more hetero atoms, said ring optionally being substituted with a C1-C4 hydrocarbon group, said process comprising reacting a compound of formula II: wherein R1, R2, R3, R4, R5, and R6 have the same meaning as defined above, with a chlorinating agent, followed by reaction with a Friedel-Crafts catalyst. The invention further relates to the preparation of the corresponding indenes.

Preparation of Benzocyclobutenones via the Photochemical Cyclization of 1-(ortho-Alkylary)-2,2,4-trimethylpentane-1,3-diones

Irradiation of 1-(ortho-methylaryl)- and 1-(ortho-ethylaryl)-2,2,4-trimethylpentane-1,3-diones 4a-g in hexane gave benzocyclobutenols 10a-g.However, irradiation of 1-(ortho-isopropylaryl)-2,2,4-trimethylpentane-1,3-diones 4i and 4j resulted in no reaction.Irradiation of 1-mesityl-2,2,4-trimethylpentane-1,3-dione 4h gave a complex mixture of products.Pyrolysis of benzocyclobutenols 10a, b, d-f gave benzocyclobutenones 11a, b, d-f and 2,4-dimethylpentan-3-one 2, whereas that of the benzocyclobutenols 10c, g gave the starting 1,3-diketones 4c, g predominantly along with small amounts of benzocyclobutenones 11c, g and the dimethylpentanone 2.

Carboxylic Trifluoromethanesulfonic Anhydrides as Highly Effective Acylation Agents. - Perfluoroalkanesulfonic Acid Catalyzed Acylation of Arenes

Arene- and alkanecarboxylic trifluoromethanesulfonic anhydrides 2 and 5 are highly effective acylation agents, which react without Friedel-Crafts catalysts even with deactivated aromatics to yield aryl ketones 3 and 6, respectively.Acylation of arenes with carbonyl chlorides 4 and catalytic amounts of perfluoroalkanesulfonic acid gives ketones 3 and 6, resp., in good yields.Under similar conditions other strong Broensted acids show a considerably smaller degree of catalytic effect.
