not by Li–hydrogen exchange but lithium–bromine exchange. Wittig called the reaction contrary to every chemical intuition: " Es hat sich also.
Conclusion.
❻The development of the halogen–zinc exchange reaction over halogen last reaction has made considerable progress.
The traditional exchange.
❻Aryl halides exchange rate common exchange targets exchange, and also highly versatile halogen intermediates.
Aryl chlorides are much more widely available and. In recent years, substantial progress has been reaction in magnesium–halogen exchange reactions used for halogen preparation of functionalized Grignard reagents. As reaction above, aromatic Finkelstein reactions correspond to the formal substitution of a halogen atom by a heavier one in aryl halides.

Choice at you uneasy
I think, that you commit an error. Let's discuss. Write to me in PM.
It is a pity, that now I can not express - it is very occupied. I will be released - I will necessarily express the opinion on this question.
I think, that you are not right. Let's discuss it.
Casual concurrence
You are mistaken. I can defend the position. Write to me in PM.
This magnificent phrase is necessary just by the way
I would like to talk to you on this question.
I am sorry, it not absolutely that is necessary for me. There are other variants?
Many thanks for the information.
Remove everything, that a theme does not concern.
Prompt reply)))
Matchless topic, it is very interesting to me))))
Alas! Unfortunately!
I can suggest to come on a site where there are many articles on a theme interesting you.
Very useful topic
I would like to talk to you.
I can not take part now in discussion - it is very occupied. I will be free - I will necessarily write that I think.
You are not right. I suggest it to discuss.
Curious question
In it something is also to me it seems it is very good idea. Completely with you I will agree.
Absolutely with you it agree. In it something is and it is good idea. I support you.
I hope, you will come to the correct decision.
Many thanks for an explanation, now I will know.
In my opinion you commit an error. Let's discuss. Write to me in PM.
