Abstract

Aromatic aldehydes bearing electron-donating groups are easily converted into their respective nitriles using NH(2)OH.HCl and TiO(2) under microwave irradiation, while those bearing an electron-withdrawing group give the corresponding oximes.

摘要

带有供电子基团的芳醛在微波辐射下很容易用 NH(2)OH.HCl 和 TiO(2) 转化为相应的腈,而带有吸电子基团的芳醛则生成相应的肟。
