N-alkoxyimidoyl iodides is described. This reaction occurs with complete retention of the imidoyl halide geometry to give single E- or Z-isomers of diaryl oxime ethers. The Sonogashira coupling of N-alkoxyimidoyl iodides and bromides with a wide variety of terminal alkynes to afford single geometric isomers of aryl alkynyl oxime ethers has also been developed. Several of these reactions proceed through
描述了通过N-烷氧基酰亚胺基碘化物的Suzuki偶联合成二芳基肟醚的单一几何异构体的高产立体定向途径。该反应在完全保留酰亚胺基卤化物几何形状的情况下发生,从而给出二芳基肟醚的单一E-或Z-异构体。还已经开发了N-烷氧基酰亚胺基碘化物和溴化物与各种各样的末端炔烃的Sonogashira偶联,以提供芳基炔基肟肟醚的单一几何异构体。其中一些反应是在无铜条件下进行的。介绍了N-烷氧基亚氨基卤化物的Negishi偶联。该Ë和ž X射线晶体学证实了九种铃木偶联产物和两种Sonogashira偶联产物的构型。
