使用
4-Nitrobenzyl chloride was used to prepare unsymmetrically N,N′-bis(substituted) 4,13-diaza-18-crown-6-ether derivatives.
-
調製方法
Chlorination of 4-nitrotoluene at 190 ℃ without catalyst gives 4-Nitrobenzyl chloride. The alternative process of nitration of benzylchloride coproduces 2-nitrobenzyl chloride and requires a difficult separation stage.

反応プロフィール
Incompatible with sodium hydroxide. [EPA, 1998]. A halogenated aromatic nitro compound. Aromatic nitro compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
