I'm pretty sure you will get the trans product; in fact Heck reactions are remarkable in their trans selectivity. You will have rotation so Pd and H are coplanar for the beta-hydride elimination, but it will be in a way that both big groups are anti to each other - thus leading preferably to the trans product.

[edit] Mechanism picture incorrect?
The picture in the mechanism shows a cis product forming, when it should be a trans product.
- Yes, you're correct. Someone needs to make a new image. ~K 17:18, 4 September 2006 (UTC)
It should also be stressed that this is the classic Heck cycle. New reports in the literature have modifications in which the catalytic species is an ionic palladium species in equilibrium with dimers or trimers. Look for works by De Vries on this topic.
Also the list of reagents and catalyst pre-cursors is greatly restricted. In fact almost every form of palladium imaginable has been tried as a Heck catalyst in a wide range of solvents and with a large variety of bases.
[edit] BmimPF6 or BF4
Under the section, ionic liquid heck reaction, it mentions bmimBF6. Could someone clarify? --Rifleman 82 17:13, 23 January 2007 (UTC)
