Chloroperoxidase catalyzes the peroxidation of primary alcohols, specifically those that are allylic, propargylic, or benzylic. Aldehydes are the products. The reaction dislays appreciable activity throughout the entire pH range investigated, namely

Bromoperoxidases do not directly oxidize the chloride ion; nevertheless, in the presence of bromide ions, chloride ions and hydrogen peroxide, bromoperoxidases react with alkenes and alkynes to produce bromochloroderivatives. This same reaction is ca

The enzymatic synthesis of α,β-halohydrins from gaseous alkenes is described. The enzymatic reaction required an alkene, a halide ion, dilute hydrogen peroxide, and a haloperoxidase enzyme. A wide range of gaseous alkenes were suitable for this rea

Dimethyl sulfoxide has been used as a nonaqueous organic solvent in haloperoxidase reactions. However, it has been found that this solvent is not inert under chloroperoxidase reaction conditions, forming the halosulfoxide, the sulfone, and the halosu

Two new substrate classes that can be halogenated by haloperoxidase have been discovered. The enzymatic halogenation of alkynes yields alpha-halogenated ketones, and the enzymatic halogenation of cyclopropanes yields alpha, gamma-halohydrins. The gen

Enzymatic halogenation of the double bond in allyl halides was influenced by intramolecular participation of the allylic halogen in the substrate molecule. Migration of the allylic halogen to the central carbon atom was observed in the enzymatic chlo

The enzymatic synthesis of vicinal, dihalogenated products from alkenes and alkynes is described. The enzymatic reaction required an alkene or alkyne, dilute hydrogen peroxide, a haloperoxidase, and molar amounts of halide ions. Vicinal dichloro, dib

Chloroperoxidase from Caldariomyces fumago catalyzes the peroxidation of alkenes to epoxides. This enzyme is the only haloperoxidase of four tested capable of carrying out the reaction. These results further establish chloroperoxidase as a unique hal

The enzymatic conversion of allyl alcohol to 2,3-bromochloro-, bromoiodo-, and fluoroiodo-l-propanols by various haloperoxidases is reported. This represents the first enzymatic transformation of an unhalogenated organic substrate to heterogeneous di
