A detailed NMR study of the behaviour of soluble polynuclear μ-oxometalalkoxides has been performed in view of their high activity and stereoselectivity in oxirane polymerization. The results indicate a rather rigid, globular coordination aggregate structure ("tecto-alkoxides"), undergoing very slow ...
For the cis-polymerization a mechanism involving a 7t-allylic polymer terminal with an intramolecular coordination of the double bond of the penultimate unit (called 'back-biting coordination) is proposed in which a cis-double bond is formed not only from anti-1t-allylic but also from the syn...
The confirmation of this view comes from studies on the initiation of ring-opening polymerization by complexes of tungsten chlorides with phenylcarbene. The latter is formed in the coordination sphere of tungsten by decomposition of phenyl diazomethane....
A mechanism for the polymerization of olefins is proposed. An essentially octahedrally coordinated ion of a transition element with empty or nearly empty t 2 g orbitals carrying in its coordination sphere one alkyl group and having one vacant octahedral position is supposed to be the active center...
In the last few years remarkable advances have been made in the field of non-cyclopentadienyl complexes as homogeneous olefin polymerization catalysts. In ... M Lamberti,M Mazzeo,D Pappalardo,... - 《Coordination Chemistry Reviews》 被引量: 40发表: 2009年 Molecular mechanics for coordination compl...
Our study examines the mechanisms by which DNA polymerase (pol) δ faithfully replicates DNA. To better understand this process, we have performed all-

Crystalline polysaccharides are abundant in nature and can be transformed into highly functional materials. However, the molecular basis for the formation of higher-order structures remains unclear. Computer simulation is an advanced tool for modeling ma
