products can be obtained in moderate to good yields, which offers practical access to five- and six-membered lactams. This protocol has predictable regio- and chemoselectivity, excellent functional group compatibility and ease of operation in air, representing a significant step-forward towards manganese-catalyzed C-C coupling.
Hydrocobaltation–dehydrocobaltation reactions in synthesis: a new approach to the controlled cross-coupling between sp<sup>2</sup>carbon centres leading to functionalised alkenes

Cross-couplingreactionsbetween two alkenes, leading to newfunctionalisedalkenes, can be brought about via‘hydrocobaltation’ of one of the alkenes followed by irradiation of the resulting organocobalt reagent in the presence of the second alkene substrate.
Indium(I) iodide promoted highly selective 1,2-addition of allyl and benzyl groups to α,β-unsaturated nitriles under sonication: a new synthesis of conjugated imines

Allyl and benzyl bromides react with alpha,beta-unsaturated nitrites in the presence of indium(I) iodide under sonication to produce the corresponding allylated and benzylated conjugated imines involving exclusive addition of theallyl/beilzyl group to the Cequivalent toN moiety.
