Smarty cat: A method for the palladium‐catalyzed γ‐arylation of α,β‐unsaturated estersviasilylketeneacetals in the absence of fluoride has been developed. The coupling proceeds with electron‐rich and electron‐poor aryl bromides and vinyl bromides in high yields with a high tolerance for other functional groups.
