Olefin Metathesis at the 244th ACS Meeting

by Daryl Allen on August 8, 2012

The 244th ACS National Meeting & Exhibition is fast approaching and will be held in Philadelphia from August 19-23, 2012. The overall theme of the fall meeting is “Materials for Health & Medicine.” Sticking with tradition, we here at All Things Metathesis will give a brief overview of some of the noteworthy olefin metathesis related material that will be presented in Philly.

First and foremost, Materia and All Things Metathesis’ very own, Rosemary Conrad Kiser will be presenting in the N-Heterocyclic Carbenes in Catalysis symposium during the afternoon session on August 20th. This is a particularly olefin metathesis heavy session with 9 of the 10 scheduled talks dealing with the topic in some fashion. The session breakdown is as follows:

  1. Siegfried Blechert will describe chiral Ru-catalysts containing unsymmetrical NHC ligands.
  2. Catherine Cazin will present her groups research using mixed Ru-NHC/phosphite complexes.
  3. Lionel Delaude will discuss some new Ru-benzimidazolylidene derivatives.
  4. Karol Grela is scheduled to give an overview of his groups’ research in the field.
  5. Gabriel Lemcoff will talk about some new methodologies using dimeric Ru-complexes and switchable catalysts.
  6. Herbert Plenio will provide insight into the ethenolysis of rubber.
  7. Renat Kadyrov will detail work done with low catalyst loading RCM studies.
  8. Rosemary Conrad Kiser will discuss the versatility of the NHC ligand in catalyst design.
  9. Michael Limbach will describe some continuous flow applications using heterogenized Ru-complexes.
  10. Wiley J. Youngs will close out the session by giving everyone a break from olefin metathesis and present research on the antitumor activity of silver carbene complexes and imidazolium cations.

For all of you metathesis junkies, the above session is being held at the Pennsylvania Convention Center in room 125 on Monday August 20th from 1:30-5:05pm. I’ll see you there…

Secondly, it wouldn’t be much of an overview if we didn’t mention the exploits of Nobel Laureates Bob Grubbs and Richard Schrock. Professor Grubbs will give two polymer focused presentations in symposia honoring current postdoc Garret Miyake (AkzoNobel Award for Outstanding Graduate Research in Polymer Chemistry) and former student Chris Bielawski (Journal of Polymer Science Award) on Sunday and Monday respectively. Professor Schrock will also give a polymer focused lecture, in the ACS Catalysis Lectureship for the Advancement of Catalytic Science Award Symposium on Monday afternoon.

Some other olefin metathesis related presentations that look interesting are as follows:

  • Susannah Scott will present work on studies aimed at understanding and improving supported perrhenate catalysts.
  • Ken Wagener will talk about some solid state acyclic diene metathesis polymerizations, while his student, Michael Schulz, will describe some metathesis based depolymerization processes.
  • Wing-Sy DeRieux, a student of Yann Schrodi, a former Materia employee and current professor at California State University, Northridge, will describe some efforts towards iron alkylidenes.

Finally, if you still haven’t gotten your fill of olefin metathesis and want to talk in more detail, please come visit us at the ACS Exposition (Booth #1719). If you stop by early enough during the show, we’ll have you take the Metathesis Challenge so that you can receive a Materia “Got Catalyst!” t-shirt… Sounds like a pretty good deal to me! Hope to see you in Philly!
