1,6-Interactions between dimethylamino and aldehyde groups in two biphenyl derivatives
摘要:
The title compounds, 2-(dimethylamino)biphenyl-2' -carboxaldehyde, C15H15NO, and 2-(dimethylamino)biphenyl-2',6'-dicarboxaldehyde, C16H15NO2, show similar 1,6-interactions [N . . .C=O 2.929 (3) to 3.029 (3) Angstrom] between the dimethylamino and aldehyde groups located in the ortho positions of the two rings, which lie at 58.1 (1)-62.4 (1)degrees to each other.
报道了原位生成的芳烃与甲锡烷基化亚胺反应以提供邻-甲锡烷基-苯胺衍生物。引入容易制备的三甲基甲锡烷基二苯甲酮亚胺作为实现芳炔σ-插入反应的有效试剂。亚胺官能团是一个已建立的 N 保护基团,插入以良好的产率和良好的区域选择性进行。由于三甲基甲锡烷基部分提供了丰富的化学,产品苯胺是后续化学的宝贵起始材料。
