Clinical course of type 1 autoimmune pancreatitis treated with/without corticosteroid and the cancer association

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 supressed. Under these conditions moderate to good yields of dimers R-R are obtained from primary acids. The mechanistic and synthetic...
