Talk:Ziegler-Natta catalyst

[edit] Mechanism
why is the C in the middle bonded to two Hs at first and only one later?
I don't think it has two Hs at first. it wouldn't work with valence either —Preceding unsigned comment added by FelixP (talk • contribs)
- You are right, there seem to be some mistakes in the picture. But I think there should be two (the activator is diethylaluminiumchloride, ethyl groups on aluminum), the binding to the metal center is an agostic bond (electrons of the bond between C and H are donated into empty metal centre bonds). --Dirk Beetstra T C 13:41, 2 August 2006 (UTC)
I am not so sure if there are mistakes here - anyway its a proposed mechanism. I suspect that the Ti-CR3-Al interactions are like those in the Al-CH3-Al interactions in trimethyl aluminium. BTW: we now have agostic complex started.--Smokefoot 22:08, 2 August 2006 (UTC)
[edit] Is this the "Ziegler Process"?
I am curious if this catalyst is what makes the "Ziegler Process"? Maury 16:31, 19 March 2007 (UTC)
