Diazotization Mechanism - Sandmeyer Reaction With Arenediazonium Salts - Diazo Coupling
This organic chemistry video tutorial provides the mechanism of the diazotization reaction of an amine group into an arenediazonium salt using aniline as an example and NaNO2 with HCl to produce HNO2 or HONO Nitrous Acid. It discusses the intermediates of the reaction such as the nitrosonium ion NO+and N - nitrosoamine It also provides the mechanism of the reduction of a nitro group into an amine using Iron Fe metal and hydrochloric acid HCl converting nitrobenzene into aniline. In addition, it provides the nitration of benzene reaction mechanism using HNO3 and H2SO4 generating the nitronium ion NO2+. It also provides the mechanism of the sandmeyer reaction converting the arenediazonium salt into a benzene nitrile molecule using a cuprous salt like CuCN by means of a benzene radical and a phenyl cation. Finally, this video provides the diazo coupling reaction mechanism using phenol.

keep up the good work proff, this is THE best chem channel I have ever visited. love from India
This Channel needs million views and millions subscribers for his hard work !!!!
Your Understanding of Chemistry is on a whole other level... Damn!!!😂🙇🏽♂
It's so perfectly congratulations Sir
It is cool you give us also the MECHANISM of a anorganic redox reaction, it's not usualy seen, I actualy failed an internship for beeing unable to find JUST one Websource saying me how the mechanism for a certain redox react was. But alas, it was not the one shown in this video (I had to search the oxidation of Toluene to benzylic acid by KMnO4) but thank you anyways, for the ones needing this metal mechanism your video is suposedly their ONLY chance.
Thanks sir u r awesome...love uh...idont watch any one othrrs vedios.... live long sir..
thank you every much
Thank u bro !!!!!!!!!!!! U saved me(literally).
Wonderful lessons very elaborate
Phenomenal. Great research on this vid, and it’s a shame mechanisms are not taught in as much detail at most, if not all, educational institutions.

my professor loves making us learn upwards of 10 mechanisms for any given exam so he can ask a multiple choice question that presents four different scenarios which are PART of any of those mechanisms. We are supposed to pick the two incorrect ones lol. I had to learn mechanism patterns so fast
Amazing!
great thank you a lot
Can you perform this reaction if the molecule has an Ester?
Why does HCl not behave as a radical with the radical nitrogen?

In n=o why does o positive doesnt attract nh2
Many thanks sir..so clear n brief...very good exp.
Important question: Where is the OH- that we are supposed to add in the reduction of nitrobenzene to phenylamine
whats the advantage of the radical mechanism of the sandmeyer reaction in comparison to the cation-intermediate? sure, it would not explain the usage of copper. but is the radical intermediate maybe more stable than the cation-intermediate?
in first step of mechanism ,why oxygen with negative charge does not abstracts h+??while reacting with nitric acid and sulphuric acid

I think its because if the O minus took the H we get OH which is a terrible leaving group where as water is a very good leaving group. In order for the OH to be gone we are gonna need to convert it into something that is a very good leaving group or it wont work.

Beacause O- is in resonance therefore it stable so the other oxygen bonded to h and n abstracts the H atom from HCl
Kindly learn to make the proper shape of benzene ring. Btw Nice explanation!

So how was your JEE?
Well sandmayer became samurai
