Feng, LZ and Gan, ZY and Nie, XP and Sun, PP and Bao, JC (2010) Highly regioselective synthesis of N-acyl-2,3-dihydropyrrole or N-sulfonyl-2,3-dihydropyrrole derivatives by nano-palladium catalyzed cycloisomerization of 1,6-dienes. CATALYSIS COMMUNICATIONS , 11 (6). pp. 555-559. ISSN 1566-7367
Porous palladium nanoparticles were prepared using a solution-phase approach. Their structures and shapes were analyzed by XRD, EDS, TEM and HRTEM. These palladium nanoparticles were used to catalyze the cycloisomerization reaction of N,N-diallylamide or N,N-diallylsulfonamide, and N-acyl-23-dihydropyrrole or N-sulfonyl-2,3-dihydropyrrole derivatives were therefore synthesized with very high regioselectivity, and in good yields. The nano-palladium catalyst showed high efficiency and it can be reused several times. A hydropalladation mechanism was proposed for this reaction.
