I've not played with the cd much, but you seem to be saying that it covers reactions. Is this correct? Thanks for a reply.

Ramazanov" Organization: Institute of Petrochemistry and Catalysis,Ufa,Russia Subject: ORGLIST: hand-made combines and distillators Dear Orglist members, Has anyone a experience to distillate (and separate) under vacuum small quantities (0.5-2.0 ml) of liquid organic compounds. Yes, there are many special columns but I haven't ones. I am interested in hand-made apparatus without fine work. I'd like to hear your opinion. Best regards, Ilfir R. Ramazanov, Ph.D., Laboratory of Catalytic Synthesis, Institute of Petrochemistry and Catalysis, pr. Oktyabrya, 141, Ufa, 450075, Russia. mailto:elf@anrb.ru Visit my homepage and find some QC software http://members.tripod.com/~ChemELF Visit our lab web page http://organomet.cjb.net __________________
The kulgaror (bulb to bulb distilation) in my opinion is the best apparatus for distilling small quantuities under vacume, however it normally requires specialized equipment. I have seen a couple of "home made" versions though. The glasware is rather simple, and the heating unit can be made from an old cannister coffee pot and the turning mechanism can be made from many different things ranging from a old windshield wiper mechanism to a rotovapor motor. I don't have the specifics of how to put this together as all of ours are store bought, but am willing to try to help whereever I can. Regards, Chris _________________ Date: Tue, 18 Jan 2000 10:41:31 -0500 (EST) From: Christopher Paul Borella Subject: ORGLIST: Nomencalture problem Dear list members, I am having a real hard time coming up with chemical names for several new compounds and would like to know if there are any powerfull auto naming programs. The compounds are macrocyclic taxoids (joining the c-13 ond c-2 positions for those of you familier with the compounds), it is a pentacyclic compound and I have already tried the auto naming features on chemdraw and beilstein, and it is too complex for both of them. Any help would be greatly appreciated. Thanks,

Dear colleagues, first of all I apologize for any crossposting. I need to synthesyze a few acetamidines (above all cyclopentylacetamidine and 2,6-difluorophenylacetamidine). Do you have any experience or suggestion concerning this topic?

ground glass joints (one inner, one outer), and a couple of pieces of glass tubing using moderate glassblowing skills. Or, the glassware can be purchase for not too much money from glassware vendors. The rotating portion can be attached to a standard round bottom flask. I've used a sand bath for heating and manual twirling during distillation (with 2 3-finger clamps to hold the apparatus steady) for a really low tech solution.

http://www.jepbol.com/sect1/dist.html The thing is useful for short-parth destillation of high-molecular-weight products. It is no good for separations of low molecular weight products. If you have to do any of this, I suggest you take a look at blueprints of commercial micro and ultramicro destillation and talk with your glassblower what he can build. __________________ Date: Wed, 19 Jan 2000 12:04:17 +0200 From: zabicky@bgumail.bgu.ac.il (Jacob Zabicky) Subject: Re: ORGLIST: Synthesis of amidines... Hello Gianluca, Possibly a Ritter-type process will do, treating the nitrile with dry HCl, possibly in dry ethanol, followed by treatment with dry ammonia. I used the method to prepare o-cyanophenylacetamide by applying water in the second step.

make as big injections as you can, collecting your fractions from the discharge port when you see them coming in the detector signals. In a few hours you may finish the separation of many 50-100 microliter injections. 2) Build a poor-man molecular still, where the vessel containing your sample is immersed in a constant temp. warm bath, say 40-50 C. At the top of the still you should have a cold finger with a collection ampoule. Apply a vacuum in the sub-torr range, and stop the operation every few hours to collect in capillaries or other convenient containers whatever came off.

I have used it for reading both Varian and Bruker formats, both of which are autodetected. It can also do export. There is a 30-day demo at http://www.acornnmr.com/ The registration can cost you from 100$ and up, depending on the level of features you need (support, 2D-processing etc.).

As soon as this section is complete I will work on the High-Throughput Screening section. Since this is a one-person effort, it is taking time to build the site.

I know about one database where you can search compounds sold by Aldrich, Sigma and Fluka. I've already tried here but I do not find some of the compounds I am interested in. Does anybody know any other way/place to look for such compounds?. Furhtermore, is there any place in the net where I can place an "order" and wait for somebody to reply to my query??. Is there any place for chemical compounds interchange between university labs??.

Dear Colleague, Sorry to bother you. I want to where could I purchase the chemical "cucurbituril" and how about the price. If it is not commercially available, who know the detailed synthetic procedure. I just have the liturature on its synthesis (JACS 1981, 103, 7367), which improve the procedure of Ann Chem 1905, 339, 1. In fact, Ph. D. thesis by N-Y Shih of U of Illinois at Chicago, 1981 has the detailed procedure, however I could not access it. Would you like to help me.
