Redox Catalysis of Halide Ion for Formal Cross-dehydrogenative Coupling: Bromide Ion-catalyzed Direct Oxidative α-Acetoxylation of Ketones
A novel catalytic approach for formal cross-dehydrogenative coupling using the redox property of bromide ion is reported. Simple bromide salts MBr can work as catalyst for direct oxidative α-acetoxylation of ketones.
