脱卤化氢

论述了乙烯基醚类化合物的三种主要制备方法乙炔法、脱卤化氢法和缩醛热分解法。

This paper discussed three methods of producting vinyl etherspreparation from acetylene , dehydrohalogenation and acetals .

另外，由于用作脱卤化氢剂的氨气的分子量小，从而在相同情况下可以大大降低副产物的量。

In addition , molecular weight of the ammonia that is used as the dehydrohalogenation agent is small , thus greatly reducing the weight of side products under the same situation .

这个反应称为Hofman消除反应，它很像卤代烷的脱卤化氢反应。

This reaction , called the Hofman elimination , is quite analogous to the dehydrohalogenation of an alkyl halide .

以傅克酰基化反应、串联的Aldol-Michael反应及Pd-催化的脱卤化氢环化反应为关键步骤，合成了低取代的二苯并并四苯衍生物（DBN）。

Low substituted dibenzo [ fg , op ] naphthacenes were synthesized by using Friedel-Crafts acylation , tadem aldol-Michael solvent-free reaction and palladium catalyzed dehydrohalogenation cyclization as key steps .
