Abstract
alpha-Tosyloxylation of ketones with [hydroxy(tosyloxy)iodo]benzene, follow ed by treatment with primary selenoamides provides a convenient method of s ynthesis of selenazoles without the use of lachrymatory and toxic alpha-hal oketones. The synthetic method is simple, mild and the yields are higher.
