Du, Juan; Wang, Xing; Wang, Hongling; Wei, Jinhu; Huang, Xuan; Song, Jun; Zhang, Junmin published their research in Organic Letters in 2021. The article was titled 《Photoinduced Palladium-Catalyzed Intermolecular Radical Cascade Cyclization of N-Arylacrylamides with Unactivated Alkyl Bromides》.Formula: C4H7Br The article contains the following contents:
A mild visible-light-induced Pd-catalyzed intermol. radical cascade reaction of N-arylacrylamides with unactivated alkyl bromides was disclosed. Photoexcited Pd complexes transfer a single electron in this protocol, and hybrid alkyl Pd-radical species were involved as the key reaction intermediates. Sophisticated bioactive oxindole derivatives bearing various substituents and substitution patterns were efficiently afforded through this approach. In the experiment, the researchers used many compounds, for example, (Bromomethyl)cyclopropane(cas: 7051-34-5Formula: C4H7Br)
(Bromomethyl)cyclopropane(cas: 7051-34-5) is used as a synthetic building block for the introduction of the cyclopropylmethyl group. It was also used in the synthesis of 1,4-dienes via iron-catalyzed cross-coupling with alkenyl Grignard reagents.Formula: C4H7Br
