Abstract
This paper describes a new chloroperoxidase oxidative activity, namely, pro pargylic oxidations. Under appropriate conditions, chloroperoxidase catalyz es the oxidation of a variety of 2-alkynes to aldehydes via alcohol interme diates. Both hydrogen peroxide and t-butyl hydroperoxide can serve as termi nal oxidants. The triple bond in the substrate is usually untouched. A free radical mechanism is proposed for the initial hydroxylation step in the ov erall reaction. (C) 1998 Academic Press.
