Organic Chemistry: Reaction of CH3COCl & C6H5NH2

AI Thread Summary
The reaction between CH3COCl (ethanoyl chloride) and C6H5NH2 (aniline) involves the formation of an acylated product through electrophilic aromatic substitution. The ethanoyl chloride dissociates into CH3CO(+) and Cl(-), with the electrophile attacking the ortho-para positions of the aniline due to its activating nature. The reaction is vigorous and may lead to tri-substitution on the aromatic ring. Clarification on the exact mechanism and potential complications in the reaction was requested, particularly regarding the role of Lewis acids. Overall, the discussion highlights the complexity of the reaction and the need for a detailed understanding of electrophilic aromatic substitution mechanisms.

Homework Statement



Give the structural formula of the organic product formed from the following reaction:

CH3COCl + C6H5NH2

Homework Equations





The Attempt at a Solution



The ethanoyl chloride will break into CH3CO(+) and Cl(-) due to polarity. Then, which part of the aminobenzene will the electrophile attack?

I don't think you can conclude that ethanoyl chloride will break by itself. We can't use a Lewis acid for this purpose as it will react with aniline.

If you somehow break the compound, the electrophile will attack at ortho-para positions as aniline group is a ring activator (infact the reaction will be very vigorous and it over-reacts to form a tri substituted compound).

I don't think ring will be involved.
 
Thanks, so what's the correct mechanism for this? Borek, could you pls elaborate on that?
 
Just googling for aniline and acyl chloride should give you the correct answer.

Lol...do you expect Borek to elaborate? He always writes one liners :biggrin:
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
