Abstract
A novel, direct Csp3 -Csp3 coupling reaction of β-chlorophenone with alkanes using 2-(tert-butylperoxy)-2-methylpropane (DTBP) as the oxidant and 2,2'-bipyridine (bpy) as the effective additive was developed. A variety of β-chloropropiophenones were well tolerated, and afforded alkylated products in moderate to good yields. A mechanistic study indicated a free radical pathway was involved in this alkyl-alkyl cross-coupling reaction.

Abstract
An In(OTf)3-catalyzed domino reaction involving sequential oxidative ring opening of aziridines by using the solvent dimethyl sulfoxide and intramolecular Michael addition has been developed for the modular synthesis of 2-aminoindanone compounds by the formation of one new C═O bond and one new C-C bond. The notable feature of this strategy includes broad substrate scope, excellent trans-diastereoselectivities, highly functionalized products, and mild conditions. The catalyst In(OTf)3 plays an important role in the formation of the indanone ring.
