Esters (mixed anhydrides) derived from aliphatic or alicyclic carboxylic acids (RCO2H) and thiohydroxamic acids 2 or 3 undergo a thermally or photochemically induced radical chain reaction to give sulphides 4 with loss of carbon dioxide.On irradiation at low temperature however, the chain reaction is essentially suppressed.Under these conditions moderate to good yields of dimers R-R are obtained from primary acids.The mechanistic and synthetic implications of these observations are discussed.
THE INVENTION OF RADICAL REACTIONS. PART XVI. RADICAL DECARBOXYLATIVE BROMINATION AND IODINATION OF AROMATIC ACIDS

Thiohydroxamic esters of aromatic carboxylic acids undergo clean decarboxylative bromination or iodination on treatment with bromotrichloromethane, iodoform or diiodomethane in the presence of a radical initiator.
