TOPIC NAME DAKIN REACTION MECHANISM SYNTHETIC APPLICATION SODIUM HYPOCHLORITE SOLUTION N.F.XIII (DAKIN’S SOLUTION) USES SIDE EFFECTS PRECAUTIONS INTERACTIONS
INTRODUCTION The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an ortho - or para - hydroxylated phenyl aldehyde ( 2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde ) or ketone reacts with hydrogen peroxide in base to form a benzenediol and a carboxylate . Overall, the carbonyl group is oxidized, and the hydrogen peroxide is reduced. The Dakin oxidation, which is closely related to the Baeyer- Villiger oxidation , is not to be confused with the Dakin-West reaction , though both are named after Henry Drysdale Dakin .
DAKIN REACTION The oxidation of aldehydes and ketones to the corresponding phenols is known as Dakin reaction . The reaction works best if the aromatic aldehyde or ketone is electron rich. The reagents used in Dakin Reaction are; Alkaline H2O2, acidic H2O2, Peroxybenzoic acid(C2H4O3), 30% H2O2 with aryl selenium compounds as activators and Urea-H2O2 adduct.
MECHANISM The MECHANISM of Dakin reaction is as follows:-
APPLICATION Dakin reaction has many useful synthetic application.
USES Dakin's solution is used to prevent and treat skin and tissue infections that could result from cuts, scrapes and pressure sores . It is also used before and after surgery to prevent surgical wound infections . Dakin's solution is a type of hypochlorite solution. It is made from bleach that has been diluted and treated to decrease irritation . Chlorine, the active ingredient in Dakin's solution, is a strong antiseptic that kills most forms of bacteria and viruses . Protect the surrounding healthy skin with a moisture barrier ointment (e.g., petroleum jelly) or skin sealant as needed to prevent irritation.
