nope. palladium black will not do the trick because it requires an oxidation cycle like the regular inert metal coupling reactions.

looks like you're stuck with palladium chloride or find another method.

Out of curiosity, would it be possible to react a primary amine with a sulfonyl group (tosylate specifically) and then subsequently use a base followed by a nucleophilic substitution with, say, iodomethane to produce a secondary amine?

Yes you can. The sulfonyl group makes the H more acidic and thus easier to deprotonate. It also locks the nitrogen lone pair avoiding overalkylation.

I realise that this board is mostly used for instructions on how to make drugs in your fucking garage, but since this is also a science board I thought that I would ask you brilliant minds for help.
I have a upcoming project, spanning a year or so, that will entail/connect almost every course I am taking. I am supposed to pick something to create, experiment, etc. and present the result to my professor(s) and peers.
I have seen dudes investigate pharmacuticals, tried to treat salmonella by destroying its flagella with enzymes, etc.
What the hell am I supposed to do?
I might be given access to chemicals, but I do not want to make drugs, even though that would be sweet.

Is there anything else than sweet sweet drugs that you are even slightly interested in? Preferably something to do with making the world a better place. Great grades coming easily if you do some shit to help african children or make an anti hangover pill.
Start with something not so specific that interests you, do some investigation and then get closer and closer to your ideea until you are drinking champange from a nobel prize while popping anti hangover pills that help african children.

Hey guys,

I want to get into chemistry. Can you recommend some good, free online courses or something? Or maybe some book(s) that is good for a self-learner? The site study.com offers a free 5 day trial (afterwards the cheapest thing is $50/month which isn't bad), I will give that one a go. On this other site, alison.com are some free courses of introduction to chemistry, which is exactly what I'm looking for, but it looks like these are only videos, I'd rather have something like videos and presentations/written text so I can re-read it and learn it.. you know, just like in college. Yeah I could make my own notices while watching the videos but fuck that noise, I hate making notices. Any suggestions?

I remember as a kid I used to mix mr muscle containing NaOH, aluminium and water. A strong exothermic reaction occurs by mixing the NaOH and water. Adding the aluminium instantly reacts with the solution and creates hydrogen gas.
Me and my friends had a blast doing it when we compressed it in a regular old plastic PET bottle (get the pun?)

Are there any similair experiments that causes the same kind of explosive result (made from homemade stuff of course)?

I've heard something about El Dorado soap but idk

I can't really make nitro glycerin like that cool youtube chemist because I don't have access to nitric acid, etc.

just put a small volume of pure ethanol in a big container and shake it around, then wait a bit and light away.

Oxycodone Reactions Summed up Neatly

Okay, so we had a failure with the reactions of oxycodone with a fucked up friend of mine a while back. He had given me some failed hydrogenated species of 14-hydroxycodeinone which was one of the weirdest highs I have ever experienced in my life. I think I took around 25mg of it.
I think that was a weird kappa-agonist with some mu-effects.

Regardless, a few things that make the last thread obsolete are as follows:
  1. 14-hydroxylation of any morphinan requires the double bond at the 7th position for the enol to occur. Otherwise, the oxyacid cannot form the tertiary alcohol due to lack of reactivity.
  2. Acetic protection group seems to be the easiest way to create 14-hydroxy on the morphinan groups. It has the most yield if not starting from thebaine. The next best thing would be an annoying Cobalt (III) salt which I never knew existed. It seems like this unstable salt can be used as a catalyst for codeinone > hydroxycodeinone. But it's really annoying to make.
With no protection, the yield is an atrocious 20%. With the protection, you can get the yield up to 80%.
3. Almost all side reaction waste products are water soluble after basifying. Unless you're unlucky, there is little requirement for columns during these reactions.
4. You cannot avoid hydrogenation if making oxy from cod.

In summary, unless you want to follow the method step by step on the erwoid page that summarises Codeine > Oxycodone, you won't produce nearly the same results with the available chemicals.
With no protection, you could easily achieve a 20% yield of oxycodone from codeine.

He's also currently working on a more efficient method to oxidise codeine to codeinone (hopefully using bleach and vinegar), a more efficient method to hydrogenate, as well as a better peroxy-acid to put the 14-hydroxy group on.

Pic related. Artefacts. We need those 1900 German artefacts that tell us how to morphine.

Thants (our br/opi/ in Canada) has recently nodded off W-18, which is a totally novel opioids that hasn't seen street time. So /chem/ might as well talk about it.

The current method of synthesis is outlined in patent no. US4468403
>A mixture of 1-phenylethylpiperdylidene-2-(4-chlorophenyl)sulfonamide (1.17 g, 3.11 mmol) W-15, 90% fuming nitric acid (3.0 ml) and concentrated nitric acid (2.0 ml) were stirred vigorously for 4 hours at 25° C.
Preparation of 1-phenylethylpiperdylidene-2-(4-chlorophenyl)sulfonamide is not outlined, unfortunately. But it's pretty easy to figure it out as it's a straight chained molecule.

So uhh ya. W-18. Talk about it. It's legal everywhere except in Sweden right now. I guess that is a thing. It was discovered by Knaus back in the 80s who was a pretty sick guy who liked opioids. He's had a lot of work doing shit like that. Here's some condensed reading:
http://chemistry.mdma.ch/synthforum/about635.html

W-18 is the 18th item on his patent list: http://www.google.com/patents/US4468403
It includes up to 35 different, unscheduled, and very potent, novel opioids that do not rely on the morphinan group. Check em.

High school chemistry class, we were working on a lab where we had to make little squares on a piece of plastic to perform tests in, and the squares had to have 2 cm long sides.

This kid at my lab table, who had already proven to be not so bright in class many times beforehand, got our teacher's attention, then asked what a centimeter was.

After the teacher thoroughly explained what a centimeter is, and where exactly to find them on the ruler in front of him, the student turned to us and said:

"I'm still not understanding this centimeter thing."

Polyethylene terephthalate can break down to form Bisphenol.
That's probably the taste and can fuck with your hormone system. Don't drink the water if the water bottle has touched hot water, just a generally bad idea.

It's not super toxic. But don't do it.
