Rapid Access to 3-Aryltetralin Skeleton via C(sp3)–H Bond Functionalization: Investigation on the Substituent Effect of Aromatic Ring Adjacent to C–H Bond in Hydride Shift/Cyclization Sequence

The concise construction of 3-aryltetralin skeleton via hydride shift mediated C–H bond functionalization was achieved. In this process, the benzylic [1,5]-H shift occurred smoothly to furnish tetralin derivatives in good to excellent chemical yields. The electronic and steric properties of the aromatic ring adjacent to the C–H bond influenced significantly the reactivity of this transformation.
