TL;DR: Poly(styryl)bipyridine, 1, is produced from the reaction of lithiated polystyrene with bipyridine in tetrahydrofuran as discussed by the authors.
Abstract: Poly(styryl)bipyridine, 1, is produced from the reaction of lithiated polystyrene with bipyridine in tetrahydrofuran. Under our conditions, bipyridine becomes bound to 1615% of the phenyl residues. The reaction of 1 with a variety of transition-metal salts can be carried out in a variety of swelling solvents and results in formation of polymer-bound bipyridine transition-metal complexes. The extent of metal incorporation depends on solvent, metal ion concentration, and the identity of the metal species. Zerovalent metal complexes such as@-Ph-bpy-M(CO), (M = Cr, Mo, W) are readily prepared from the reaction of 1 with the metal hexacarbonyl complexes. (Poly(styry1)bipyridyl)palladium acetate is an active catalyst for the hydrogenation of olefins at ambient pressure and temperature. It can also be used to catalyze the acetoxylation of benzene; however, the percent conversion in this case is rather low.

TL;DR: The first total synthesis of triterpene ether teurilene using two vanadium-(V)-catalyzed oxidation-cyclization reactions with different stereoselectivities was reported in this paper.
Abstract: The first total synthesis of the triterpene ether teurilene has been accomplished utilizing two vanadium-(V)-catalyzed oxidation-cyclization reactions with different stereoselectivities. The synthesis involved stereoselective and step-by-step construction of 2,5-cis- and 2,5-trans-tetrahydrofuran rings, vanadium (V)-catalyzed oxidation of 4-substituted 4-en-1-ol and subsequent cyclization of the resulting anti-epoxy alcohol, and a similar oxidation-cyclization of 5-substituted 4-en-1-ol by way of syn-epoxy alcohol. An improved synthesis of 1, which featured direct formation of bis(tetrahydrofuran) from squalene derivative by simultaneous double oxidation-cyclization, was also accomplished

TL;DR: Reaction of lanthanum with Hg(C6F5)2 and bulky N,N'-bis(2,6-diisopropylphenyl)formamidine (HDippForm) in tetrahydrofuran gives a rare terminal Ln-F bond, and a high yield of a novel functionalized formamidine, DippForm((CH2)4OC6F4H-o).
