摘要：
alpha-Tosyloxylation of ketones with [hydroxy(tosyloxy)iodo]benzene, followed by treatment with primary selenoamides provides a convenient method of synthesis of selenazoles without the use of lachrymatory and toxic alpha-haloketones. The synthetic method is simple, mild and the yields are higher.
