Herein, Rh-catalyzed benzylic addition of alkylarenes to Michael acceptors for the formation of C(sp3)-C(sp3) bonds was reported. The catalyst was proposed to activate the aromatic ring via η6-coordination, dramatically facilitating deprotonation of the unactivated benzylic C-H bond and addition of the resulting carbanion to the α,β-unsaturated double bond in the absence of bases. Notably, this byproduct-free method provided an access to all-carbon quaternary centers through the development of ligands. In the experiment, the researchers used many compounds, for example, 2,3-Dihydrobenzo[b]furan (cas: 496-16-2Name: 2,3-Dihydrobenzo[b]furan).
2,3-Dihydrobenzo[b]furan (cas: 496-16-2) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. Benzofurans are stable towards alkali and readily polymerize on treatment with sulfuric acid, due to which they are useful for the preparation of low cost chemically relatively inert resins.Name: 2,3-Dihydrobenzo[b]furan
