Cationic NHC–Pd (NHC = N-heterocyclic carbene) complex-catalyzed cycloisomerization of dienes

Various (NHC)Pd(η 3-allyl)Cl complexes possessing different NHC ligands and allyl groups are utilized for the cycloisomerization of simple 1,6-dienes to afford the desired cyclized product with an excellent selectivity. A variety of [(NHC)Pd(η 3-allyl)]Cl (NHC = N-heterocyclic carbene) involving dif...

Description
Summary:Various (NHC)Pd(η 3-allyl)Cl complexes possessing different NHC ligands and allyl groups are utilized for the cycloisomerization of simple 1,6-dienes to afford the desired cyclized product with an excellent selectivity. A variety of [(NHC)Pd(η 3-allyl)]Cl (NHC = N-heterocyclic carbene) involving different allyl groups and NHC ligands were synthesized and employed for the cycloisomerization of 1,6-dienes to form cyclic compounds selectively.
