This video has everything! Dean Stark, multiple diy reagents, mercury, crazy looking molecules, amalgamation, vacuum distillation, impurity, reducing an oxide layer, nitrogen balloon, and even a sweet cameo by sick boilover itself! on a scale of 1 to 10 this one's a 25 bruh! Can we just appreciate the effort he puts into keeping us on the edge of our seats for 11 minutes with ethoxides? This one's a banger!

Loved the in depth discussion for the last mechanism on this one. The mark of a true organic chemist.

it amazes me every time how much time and effort is spent on every chemiolis video...

very based move of linking the procedures via scihub in the description

Fun fact, reciprocating steam engines use a device like that Dean-Stark trap, but to cause accumulated water to lift a controlled quantity of lube oil into each cylinder.

Always nice to see new and safer reagents come along, looking foward to seeing how it compares to NaBH3CN!

@@mduckernz I have yet to see anything on its EHS or LCA so even if it could be manufactured safely and with minimal waste that still says nothing about the waste itself or what happens once it's actually used, and unless it's perfectly catalytc (see AlCl3 which might as well have to be added stoichiometrically) the waste/product mass ratio is meh

It is nice to see pentacoordinate Silicon compounds get more attention. They are pretty neat

Boratrane can be made by just heating boric acid and triethanolamine neat at 200C for a few hours until the mix solidifies

I am so insanely jealous of your glassware, your beautifully stocked lab, and your knowledge. So very fucking jealous.

This video was incredibly cool. Group 13/14 elements are very powerful and understudied as catalysts

this is awesome I just today had my organic chem lecture about reductive amination. I feel supremely nerdy for this but i dont remember another time i've been this hype for an upcoming yt video

Cool vid mate! Well done!

Cyanoborohydride is a pain because you need to do purification afterward. Is this easily removable?

This is amazing!

Since you're heating it anyway and just trying to amalgamate the aluminum to increase surface area, can you just substitute the mercury with gallium so you don't have to risk using a toxic metal?

Using mercury to react the aluminum seems like the spiciest way to do this reaction, although probably also the easiest.

Holy shit this took so much effort this is so good

Why mercury instead or iodine to remove the passivation oxide layer>?

Amazing video. Thnx buddy🎉🎉🎉🎉❤

Could you try making the alkyl variant of this substrate to see if it can do hiyama couplings?

Maybe doing it, mixing in some slurry, adding some carbonation or something that feels like it makes you tongue "tingle" like an electric shock is my end goal if my stomach can take that.

@andym.s.5231

_cries in point group symmetry and ligand field theory_

does this also reduce aldehydes? the favorable advantage of cyanoborohydride in these reactions is that it doesnt fight against the aldhyde like nabh4 does.

Ooooh nice and fluffy silicon oxides at the end! Just don't breath it in.

I get the purpose of iodine but I don’t understand why is it important to use mercury chloride to the solution to create an amalgam. As long as Aluminum is exposed out of the oxide layer, the reaction should follow suit or did miss something?

0:33 that alone makes it worth replacing LAH in lab settings at least, if it weren't for cost, same going to the borohydride and such

Nice synthesis and structure. Reminds me of pyrrolizidine alkaloids of my PhD. Is this dark background the inside of a hood? I hope it is!😉👍❤

STAB is super useful though, I always make mine in situ from acetic acid and NaBH4

I came across an interesting molecule you should try synthesizing! It’s called Iceane, and is an obscure carbon structure that has the same base structure of a mineral found only in meteorites called lonsdaleite which is (theoretically) stronger than typical diamond.

Dude cool Love your videos Have you thought of using a huber ministat and a jacketed flask for the temperature sensitive stuff? (Lot of coin but can be done semi-cheap if you get creative)

I plan to use something like that for cooling very exothermic reactions like nitration, but coolers are a bit pricey to justify atm

Damn those three dimensional reagents are fancy

I don't understand chemistry but I love learning things I don't know.

You can also find boric acid in the feminine hygiene section.

As an inorganic chemist, I also have no idea how that reaction works.

This channel is becoming more and more of a "How to speedrun Pihkal"

Uuuu, sounds good from the getgo

pretty sure triacetoxyborohydride would be easier to synthesize from sodium borohydride

7:18 Couldn't we just used _sodium ethoxide_ would had made sodium chloride instead of HCl. If i most say, some inorganic compounds are special in organic chemistry, opens up more possibility that can take shortcuts to building molecule.

Reductive amination? Don’t mind if I do…

Neat, but realistically, I don't see this replacing traditional reducing agents. Borohydrides are just so cheap, versatile and easy to tune. Instead of buying cyanoborohydride, I'd just add 1 equiv of NaCN to my reaction and it works just as well.

Hm maybe I could make this one: “First add toluene” - good I got that “Then boric acid” - cool I have a kilo of that, so far so good “Then triethanolamine” - shit…
