Palladium pop rocks: Hold on to your CO2! Enantioselective palladium‐catalyzed decarboxylative alkylation of ketone enolates proceeds via η1‐σ‐allyl palladium–carboxylate complexes, such as 1 (Pd yellow, O red, N blue, P purple), by slow loss of CO2. Reminiscent of pop rock candy, impure samples of 1 expel a gas (presumably CO2) in the solid state and effervesce in solution.

羧酸盐络合物进行,例如1(Pd 黄色、O 红色、N 蓝色、P 紫色),通过缓慢损失 CO 2。让人想起流行的冰糖,1 的不纯样品排出固态气体(可能是 CO 2)并在溶液中泡腾。
