Gobs of globules : A polymeric imidazole/acrylamide palladium catalyst, MPPI‐Pd (M=Pd II Cl and Pd 0 ), was utilized for the allylic arylation/alkenylation of allylic esters with aryl/alkenylboronic acids and tetraaryl borates. Low catalyst loadings efficiently promoted the reaction with a catalytic turnover number of 20 000–1 250 000. The catalyst can be reused without loss of catalytic activity.
