Making a Secondary Alcohol Called Benzhydrol 

you cannot just TLC stuff with an rf of 0.9 and assume it worked - you need to use a less polar eluent, otherwise everything will come together in one big blob

this can also be made with the Grignard reaction using bromobenzene and ethyl formate, if you don't have access to benzaldehyde ☺

Oh... I remember one of my university synthesis... it was triphenylmethanol... through Grignard reaction. Funniest part was to prepare Grignard reagent (slowly adding Ph-Br to magnesium in dry diethyl ether. Reaction is exothermic and starts suddenly... one must not miss the moment to put ice bath)

Grignard is more fun, but reducing benzophenone with Zn powder is easier and a lot cheaper...

06:38 Same with DCM. It's cool, to have it in your hands, mildly heat it and it starts boiling.

I dont know why, but benzhydrol looks like it would smell fresh

Big time organic synthesis very nicely done

A chemistry teacher I know always tried to recover bromine from the MgBrCl waste after performing reactions with Grignard compounds

I can see an Aussie chemist coming to spank you for calling beautiful yellow product. btw pretty good synthesis love your videos as always Also you should have seem tlc by Tom from cubane series where he uses flame to stretch the capillary tube to make it thinner

Great and educational video as usual. Also very happy that you upload so frequently!

This molecule looks like a bike

A clever fellow. The use of magnesium in other reactions powered much of the Swiss economy during the early parts of the last century. Cosmetics and flavorings. And the manufacturing of heroin and meth. The laws and attitudes were much different then. See the PBS Documentary 'WW Speed,' as a reference.

Thank you very much!

organomagnesium chemical reactions are always interesting.

Dude those spots on the tlc are the size of a tennis ball :D

Seeing that tetraphenylethylene molecule reminded me of Gomberg's dimer, the stable, persistent triphenylmethyl radical, as well as tetraphenylmethane. Could you try synthesizing those? :-D Edit: Nice video, by the way! I have one question, however: seeing you use a grignard reagent instead of reducing benzophenone has me wondering if you have no benzophenone?

a nmr and hplcms spectrum would be quit convenient.....

+THYZOID LABORATORIES Do you think you can do an extraction of magnesium (it doesn´t need to be elemental magnesium, a magnesium salt is fine) from sea water?

Any reason you used 4A molecular sieves instead of the more typical 3A?

Gotta love that yellow chemistry lol

I love me some greeknut reactions

Modafinil is a good project over all just make sure you pay attention to the crystal lattice of the final product I got this sorted out years ago so most patents came to me with an optimized or at least played with procedure by another peer like somebody who Isn't me as well as someone else swim SE... Internet litterature work's

I keep having a problem with drying ethanol with 3a molecular sieves, everytime I add the sieves after the proper sitting time the ethanol is always cloudy! And I can't filter it out whatsoever! What am I doing wrong? I'd appreciate you're opinion!

Your channel is awesome! How the heck do you have all of these great Chems????

That was a big ass funnel.

Well, the reaction to make the grignyard reagent isn't called the grignyard reaction, but the reaction to make the alcohol is. btw can you make more organic synthesis videos?(like a tutorial?)

Wonderful video, how do you plan on doing the olefination? Oxidation and then Wittig?

Try 3A MS. They are best for drying.

Interessant. How does it smell? Kannst du mal p-toluolsulfonsäure herstellen?

Been storing you Mg turnings close to your acid storage?

Are you planning on making DPH? I've been planning on trying that sometime in the future.

Nice One !

Why don't you tey making diphenhydramine(benadryl) using this compound it would be interesting!

cool

What is this used for?

thyzoid: *uses benzaldehyde in his amateur chemistry experiment* Me: oof... good thing he doesn't live in the land of "freedom" (Benzaldehyde is an illegal precursor in the United states of quote/unquote "freedom")

Wouldn't have been easier a reduction of benzophenone?

"greeknart" ? Its Grignard. I spell it like "Grinjar"

Just a quick remark: "Grignard" is a French name and is pronounced "Gri-ni-ar".

yelow chem bad

Your addition order seems somewhat strange, although in this case it doesn’t matter. Wonderful video anyway! 🧪💚
