2-Phenacylindan-1,3-dione (3) was treated with Lawesson's reagent (2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide) to form 2-phenyl-4H-indeno[1,2-b]thiophene-4-one (4). Compound 4 was subsequently reacted with hydroxyl amine to form t

Unusual and Competitive Side Reactions during C-Alkylation of Indan-1,3-dione

Direct C-alkylation of indan-1,3-dione (I) with reactive alkyl halides under mild conditions leads to the formation of 2-alkyl-indan-1,3-dione (II) along with bis-alkylated derivative (III) and traces of 2-alkylated bindone (a self-condensation of indan-1,3-dione).The isolation and characterisation of these compounds are described.
