Peroxyseleninic acid

The actual oxidant may be peroxyseleninic acid, H0Se(0)00H, which is known to oxidize secondary amines to hydroxylamines.

Peroxyseleninic acids. Treatment of a mercurated 2%-crosslinked polystyrene with selenium dioxide affords a yellow polymer (Equation 6) which has been assigned the structure of polymer-bound phenylseleninic acid (32).

A PS-peroxyselenic acid (29) was prepared by treatment of PS-mercury(II) chloride (30) with selenium dioxide followed by 30% hydrogen peroxide (Scheme 10). In a triphase system, consi ting of (29) (1.5 mol %), 1.5-1.8 equivalents of 30% aqueous hydrogen peroxide and dichloromethane, alkenes were oxidized to 1,2-diols, and ketones to esters or lactones. The polymeric seleninic acid (31) could be reoxidized to the PS-peroxyseleninic acid (29) and recycled with no apparent loss of activity.
