La 反应催化剂 par le palladium d'halogenures allyliques avec des reactifs aryl- etvinylstannanes donne des produits de copulation croisee。En存在 de monooxyde de carbone, des cetones sont obtenues, result d'une copulation croisee accompagnee d'une insert de CO. La反应 est douce et s'effectue meme en 存在 de differents fonctions (OH, OR, CN, CO 2 R , CHO) soit sur le le chlorure allylique soit sur le stannane

Gobs of globules: A polymeric imidazole/acrylamide palladiumcatalyst, MPPI‐Pd (M=PdIICl and Pd0), was utilized for the allylicarylation/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.

uniformly dispersed in MEPI-Pd. MEPI-Pd was utilized for the allylic arylation/alkenylation/vinylation of allylic esters and carbonates with aryl/alkenylboronic acids, vinylboronicacid esters, and tetraaryl borates. Even 0.8-40 mol ppm Pd of MEPI-Pd efficiently promoted allylic arylation/alkenylation/vinylation in alcohol and/or water with a catalytic turnover number (TON) of 20,000-1,250,000. Furthermore
