Selenophenes, dioxirane oxidation

Selenophenes, dioxirane oxidation, 1157 Selenyl radicals, triplet oxygen domino reactions, 223, 227... 

Little has been reported on the oxidation of selenium functionalities by dioxiranes. One case is the oxidation of selenophenes by DMD " at subambient temperatures. Good yields of either the selenophene 1-oxide or 1,1-dioxide may be achieved, which depends on the amount of DMD used (Scheme 12) . These results are similar to those already presented for the sulfur congeners. ...
