is of great importance in synthetic and green chemistry. This study describes the synthesis of benzo[ d ]azol-2(3 H )-ones such as benzo[ d ]thiazol-2(3 H )-ones, benzo[ d ]oxazol-2(3 H )-ones, and benzo[ d ]imidazol-2(3 H )-ones using 2-phenoxycarbonyl-4,5-dichloropyridazin-3(2 H )-one in one pot. The reaction reported is carried out under neutral or acidic conditions in the presence of zinc or sodium
开发环保、稳定且易于处理的酰基来源在合成和绿色
化学中具有重要意义。本研究描述了苯并[d]唑-2(3H)-酮的合成,例如苯并[d]
噻唑-2(3H)-酮、苯并[d]
恶唑-2(3H)-酮和使用 2-phenoxycarbonyl-4,5-dichloropyridazin-3(2 H )-one 在一锅中合成苯并 [ d ]imidazol-2(3 H )-ones。报道的反应是在中性或酸性条件下,在
锌或
碳酸氢钠存在下进行,以良好到极好的收率得到相应的杂环。该反应使用固体稳定的羰基源,它是一种可回收的官能团载体,
