Pd-catalyzed coupling: possible catalyst posions.

Are there any well-known posions/deactivators for Pd-catalyzed coupling reactions? I think I read once that MeOH might deactivate such reactions, but I'm not able to find any articles on the subject. Does anyone have any input?

MeOH is complete nonsense. As Pd poisons/deactivators are actually known:
Sulfur-containing substances (there is a hydrogantion using diphenylsulfide as poison), amines and of course air (leading to Pd(II)-species).

Lead salts and quinoline are fairly widely used
