Mild Aerobic Oxidative Palladium (II) Catalyzed C-H Bond Functionalization: Regioselective and Switchable C-H Alkenylation and Annulation of Pyrroles
Elizabeth Beck et al.
Journal of the American Chemical Society 128 (8), 2528-9 (02 Feb 2006)
 
A Strategy for C-H Activation of Pyridines: Direct C-2 Selective Alkenylation of Pyridines by Nickel/Lewis Acid Catalysis
Yoshiaki Nakao, * Kyalo Stephen Kanyiva, and Tamejiro Hiyama
Journal of the American Chemical Society 130 (8), 2448-9 (05 Feb 2008)
Lewis Acid activation of pyridine results in C-2 selective alkenylation to give functionalized pyridines. Diorganozinc catalyst gives monoalkenylation product whereas AlMe3 gives dienylated product.
 
Efficient 1,2-Addition of Aryl- and Alkenylboronic Acids to Aldehydes Catalyzed by the Palladium/Thioether-Imidazolinium Chloride System
Masami Kuriyama, * Rumiko Shimazawa, and Ryuichi Shirai
the Journal of Organic Chemistry 73 (4), 1597-1600 (11 Jan 2008)
1,2-addition of aryl, heteroaryl, alkenylboronic acids to aromatic, heteroaromatic, and aliphatic aldehydes is effected in the presence of palladium with thioether-imidazolium chloride ligand, in good-excellent yields.
