I purchased the Sigma 2x EX DG APO Autofocus and looking for to buy the Tokina 400mm AT-X AF lens, does it work on my Nikon D700?

Even if it fits, you're talking about creating an f/11 lens that surely won't autofocus and will want to be stopped down a couple of stops from wide open--which suddenly is at f/22. Not a good idea.

I've had the Tokina in Canon mount and it was a remarkably good lens for the price. I would not suggest it with a 2x TC, though.

what about Tamron lenses? How do I know if the extender will compatible with a specific lens or not?
