Mechanistic and Catalytic Behavior of Os for the Chlorpheniramine Maleate and Bromamine-B Redox System
Abstract: Chlorpheniramine maleate (CPM) is an important antihistamine agent. To the best of our knowledge there is no report in the literature about the oxidation of CPM with halogen + 1 oxidant from the stand point of its kinetics and mechanistic chemistry. Hence, a systematic kinetics and mechanistic study on the oxidation of CPM with bromamine-B (BAB) in the presence of NaOH and Os(VIII) catalyst has been carried out at 303 …
