Abstract
Abstract 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 2 H -1,4-benzothiazin-3(4 H )-ones and 2 H -1,4-benzoselenazin-3(4 H )-ones, respectively, in moderate to high yields under mild conditions.
