Mono-telechelic polymers by catalytic living ring-opening metathesis polymerization with second-generation Hoveyda–Grubbs catalyst

Liu, Peng ; Dong, Zhenghao ; Kilbinger, Andreas F. M.

In: Materials Chemistry Frontiers, 2020, vol. 4, no. 9, p. 2791–2796

The second-generation Hoveyda–Grubbs (HG2) catalyst, which has a small initiation to propagation rate ratio (ki/kp) in ring-opening metathesis polymerization (ROMP), was successfully used in a recently developed catalytic living ROMP. This proved that slow-initiating catalysts can enable ROMP in a living fashion to produce polymers with narrow dispersity and controlled molecular weight. The...

Catalytic living ring-opening metathesis polymerization with Grubbs’ second- and third-generation catalysts

Yasir, Mohammad ; Liu, Peng ; Tennie, Iris K. ; Kilbinger, Andreas F. M.

In: Nature Chemistry, 2019, vol. 11, no. 5, p. 488–494

In a conventional living ring-opening metathesis polymerization (ROMP), an equal number of ruthenium complexes to the number of polymer chains synthesized are required. This can lead to high loadings of ruthenium complexes when aiming for shorter polymers. Here, a reversible chain-transfer agent was used to produce living ROMP polymers from norbornene derivatives using catalytic amounts of...

Novel iron tweezers complexes for hydrogenation and polymerization of olefins

Mafua, Roger ; Jenny, Titus A. (Dir.)

Thèse de doctorat : Université de Fribourg, 2006 ; no. 1503.

L’utilisation des complexes organométalliques comme catalyseurs est devenu un domaine très important de la chimie des matériaux. Cependant et malgré ce développement, les catalyseurs à base de fer(II) sont peu employés dans la polymérisation d’oléfines. Un de rares catalyseur utilisé dans ce contexte est le complexe tridenté diimine pyridine développé par Gibson et Brookhart....

Heptacoordinate Co(II) catalyst for light-driven hydrogen production in fully aqueous medium

Lucarini, Fiorella ; Ruggi, Albert

In: CHIMIA International Journal for Chemistry, 2018, vol. 72, no. 4, p. 203–206

Photocatalytic hydrogen production is an appealing way to store solar energy as chemical fuel. The most studied molecular catalysts for H2 production are based on earth-abundant metals such as Ni, Co and Fe. Efforts have been recently focused on the design of Co complexes with distorted octahedral geometries induced by tetra- or pentapyridyl ligands. We synthesized a new Co(II) complex based...
