looks good, but it would be nice if summaries would take place to cut down on numbers of articles on your site. (summarize the stuff thats been around a while)

Looks good? Looks fantastic !
I fell in love with nr 8, Alumina/Sodium, especially the continuous operation, the moment I saw it. That's a totally new one to me.
The extensive instructions in the patent, how to prepare the catalyst, makes that an easy one.
And the 1-Butanol + 4M KOH in conventional reflux 15 minutes, 99% conversion, in nr 9, that's a fine one too.
Nr. 7, solventless PTC variation is covered here in my sticky thread extensively, it originated from a Osmium post last year. LT/
PS: Yes, I agree, there are some really old techniques covered on your fine site, which can send newbees hayward, if they didn't grab the more recent posts on those various methods.
Some cleaning up wanted, but I realize it is a lot of work for you, and you seem to be a buzybee.

Summarize? Do you mean merging the separate documents covering several methods of doing the same thing into review articles like the one above? I will not remove anything from my page though, if the method isn't proven NOT to work.
If you give me detailed suggestions on how to improve my site, I'll be very glad. I am planning to turn all the documents into HTML format, to facilitate easy reading and to ensure that I get more hits from my own and third-party search engines.

a good way to summarize would be by drug chemical family (as in chemical structure not pharmacological type)
Eg.
amphetamines
opioids
(dissociatives-don't know how to call them)
THC- relatives
etc.
then for precusors list them into chemical families
alkyl halides
oxidizing/reducing agents
alcohols
amines
2,5-sub pattern chems
3,4,5-sub pattern chems
allyl compounds
alkanes
(obviously this isn't detailed description as you called for, but obit. didn't think that the suggestion would be backed up by any other bees so obit is not prepared)

Yep, not so clear what I meant in my PS.
ALL contributions to your site should have the original posting date in it, so we can see if it is a really old method, which has been covered more recently with some improvements or additions.
These improvements could be linked to there at the bottom then with that nice addy from Lili like
We can much easier attent you to these improvements when you have converted all of them in HTML, and then you can use ev. the HTML posts in the forums here, or doesn't that work?
That will improve page hits to your and our site!An example :
The One Pot Methamphetamine ICE post there is not the same as the latest one. See sticky thread. Made some small but essential changes.
Sorry, it's all in the edit mode done, so you get no new postdate or (1) behind the posts in the forum. Many other edits have been made to those One Pots lately.
The Big scale Leuckart should read instead of 90°C : 60-65°C. That could save some experiments.
Yes, should have mentioned it earlier, but every time I forget it again.
You mentioned the intention to place the sticky thread up there on Rhodium's, asked me if I could convert it to HTML (wtf, it's allready HTML, but a la) so Zooligan offered to get it done, never heard anything from that project anymore. I don't have the skill for it.
In that thread are many improvements to f.e. One Pot Boro methods and Classic performic.
And there will come more for the AA and NH3 ones, I promise.
Btw, am working on it now to get the formatting right again, during many software glitches that has been somewhat chaotic returned from the database.
And working methods, whatever yield, should stay there forever. LT/

Obit: Okay, I have now divided my precursors section into "Organic" and "Inorganic" precursors, which will hopefully help the navigation somewhat.
LabTop: I can not use the HTML code from the Hive at my page, as we use different layout schemes (My layout will become more and more consistent, and will all look like the Safrole Isomerization Review when I'm done with them.
Other changes:
* Updated the ICE synthesis document at my page from the one in your sticky thread
* Added Sunlight's 10% MeNH2 preparation from your sticky thread.
* Changed the distillation temp for methanol to 60-65°C in your huge scale Leuckart writeup.
Other than that, you need to specifically tell me what needs to be updated, and preferably send the writeups to me separately method by method, as I have no idea what you have changed and what you have not. I don't have the time to check your sticky thread and compare what's written there word by word with the docs on my page, but if you continuously inform me of updates (Not just "the sticky thread is updated", but more like "In step 5 of the bla blah method, the amount of solvent has been changed to 50ml").

Thanks for the updating, and you will get the next ones as you proposed, boss.

I am continually amazed.

I counted to 63 new links this month on the chemistry archive page alone (it's only on that page I bother to add that "New" icon). I also installed a javascript which automatically removes that icon from the page when the link has been there for a month or more.
I am open to other suggestions - let yourself loose!

Other than the first route, the other methods aren't ranked in a special order.

In the vac reflux isomerisation it says don't use more than 800ml in a 1L flask. That's wrong.
1.) For 800-1000ml use a 2L flask
2.) Bigger reactions than that have the tendency to bump violently, apparently magnetic stirring isn't good enough anymore.
(For our industrially oriented bees: using a capillary to introduce a stream of air bubbles, comparable to good oldfashioned vacuum distillation should work to circumvent the batch size limitation).
