Synergistic control over the SH2 transition states of hydrogen abstraction exploiting polar and steric effects provides a promising cooperative strategy for site-selective C(sp3)?H functionalization using decatungstate anion photocatalysis. By using this photocatalytic approach, the C?H bonds of substituted lactones and cyclic ketones were functionalized selectively. In the remarkable case of 2-isoamyl 4-tert-butyl cyclohexanone (1 t) bearing five methyl, five methylene, and three methine C?H bonds, one methine C?H bond in the isoamyl tether was selectively functionalized.
