Subject: ORGLIST: New Video lecture by Ian Fleming
We are delighted to announce a new chemistry video lecture, by Ian
Fleming from the University of Cambridge, on
"Stereo Control in Organic Synthesis using Silicon Compounds"
Its at http://www.ch.ic.ac.uk/video/
(or directly at http://www.ch.ic.ac.uk/video/fleming/ )
We also introduce the use of SVG graphics, to allow the best possible
resolution for the lecture slides. You will need an SVG plugin
(and eg Chime/Chem3D) to take full advantage of the lecture.
We will also shortly introduce a SMIL (Synchronised Multimedia Integration Langauge)
version, once one particularly difficult bug is resolved.

Why don’t you try a search engine before sending such a
question to ORGLIST ?
I simply looked for 'estolide' in GOOGLE (www.google.com)
and found several useful links that answer your question (I
will not tell you the answer, anyway! :-)

Hello everybody,
I would be grateful if someone could suggest some literature
references (or would be interested to discuss details) regarding
methods to analyze polyethylene and polypropylene by FTIR and
NMR (such as degree of crystallinity, branching and so on). Thanks,

Hello
I will like to synthetize methyl cyclohexane from methyl cyclohexanone. I will like to know if it is posible to do in just one step.I would greatly appreciate anyone who can point me to good references on this, because I have searched in some books with no success.
Thank you

Subject: ORGLIST: Synthesis Approach
Hello, all. I am trying to synthesize compounds with the following
molecular structure: RBrC(double bond)CBrR, where the halogens are
preferably trans to each other. An example would be
trans-2,3-dibromo-2-butene, which would have pendant methyl groups.
Ideally I'd like to have control over the identity of the alkyl groups,
which would hopefully come from commercially available precursors (alkyl
bromides, alcohols, aldehydes, etc).
So far I've tried transforming trans-2,3-dibromo-1,4-dihydroxy-2-butene
into the 1,2,3,4-tetrabromo-2-butene with PBr3, followed by reaction
with alkyl Grignard reagents. However, this gives me a complex mixture
of (allylic rearranged) products. While I can make the dialkoxy
versions easily, they are not any good for my particular reaction, they
have to be alkyl.
Does anyone have any experience in this type of synthesis that would
like to share? All opinions gratefully :) accepted via email. Thanks
in advance!
Glen Brizius

Subject: ORGLIST: about reduction
Dear Orglist Members:
I just finished the reduction of azido group (R-N3) into amine (R-NH2) using
PPh3 in MeOH. According to the scale of R-N3 I used, more than 11 ml of N2
should be obtained. I used one empty balloon to check how much the gas I
would have, but, to my surprise, the balloon was always empty. However, some
other references introduced the same reductive reagent, but first reacted in
THF then add some water. In these paper, the authors suggest that we can
infer if the reduction completed or not just according to observe if the N2
bubble was stopped. Finally, The yield of this reduction using PPh3/MeOH is
over 80%, while nearly nothing when trying the system of PPh3/THF/H2O. Can
you explain it? Then email me your possible mechanism. Thank you.

www.chemfinder.com
is a good place to start. Beware however. I've spoted several errors in the
