Mita, Tsuyoshi published the artcileCo-Catalyzed Direct Addition of Allylic C(sp3)-H Bonds to Ketones, Computed Properties of 503538-69-0, the publication is Organic Letters (2017), 19(21), 5876-5879, database is CAplus and MEDLINE.

By using Co(acac)2/Xantphos with AlMe3, the C(sp3)-H bonds of allylarene derivatives were cleaved for reaction with various ketones, affording the homoallylic alcs. in moderate to good yields. The branch/linear selectivity depended on the steric and electronic factors of the ketone electrophiles. The intermediate in this reaction is thought to be a low-valent allylcobalt(I) species, which exhibits high nucleophilicity toward ketones.
