摘要

Bis (o-nitrophenyl) disulfides or diselenides were easy to reduce by samarium (II) iodide to produce the active intermediates 2 in situ, which readily react with α-halocarboxylic derivatives to yield the corresponding products 2H-1, 4-benzothiazin-3 (4H)-ones and 2H-1, 4-benzoselenazin-3 (4H)-ones, respectively, in moderate to high yields under mild conditions.
