Herein, we report a green, chromatography-free Appel chlorination and bromination in both catalytic and stoichiometric form. Improved sustainability was achieved via the effective replacement of chlorinated solvents with dimethyl carbonate and the use of triphenylphosphine oxide (PPh3O) as a recyclable organocatalyst. The substrate scope of this halogenated solvent-free reaction was shown to be analogous to a contemporary methodology, and removal and recovery of PPh3O from the desired products were effectively demonstrated. Investigations into the catalytic cycle were conducted, and REACT-IR was demonstrated to be an effective method of reaction monitoring in situ. Optimized methodology was applied to the synthesis of 1-bromo-4-(1-bromoethyl)benzene, a key building block employed during the discovery of a GSK fatty acid synthase inhibitor.
