Electrophotochemical cerium catalysis enables a versatile redox-neutral method for the ring-opening functionalization of cycloalkanols. The reaction tolerates a broad range of functional groups. Even in the presence of chloride as a counteranion and electrolyte, this protocol selectively leads to the formation of C-CN, C-C, C-S, or C-oxime bonds instead of a C-halide bond after β-scission.
