Furthermore, a single-electron transfer (SET) process ensues when 1 equiv of CuI is added to 1 to yield the Th(VI) bipyridyl iodide complex (Cp3tBu)2Th(I)(bipy) (3).Dongwei WangYi HengTongyu LiWanjian DingGuohua HouGuofu ZiMarc D. Walter...
The reaction of LaCl_3 with 3 equiv of KCp′ in Et_2O gave the unsolvated Cp′ _3La, while the same reaction in rigorously dry THF gave solvated Cp′_3La(THF). The reaction of LaCl_3 and KCp′ in improperly dried THF gave the mixed-ligand complex Cp′ _2CpLa(THF) (Cp = C_...
The 1H NMR spectra of 5 and 6 similarly showed six methyl signals for the Mes groups, two methyl signals for the pinacol moiety, two tBu signals and four aromatic CH signals, because they are regioisomers with the same combination of the substituents and are close in symmetry of molecule. ...
As a result, an unexpected additive effect was observed: the addition of norbornene (B2000 equiv to Ti) to the reaction mixture improved the catalytic activity, and the resulting ethylene/norbornene copolymers had high molecular weights and relatively narrow Mw/Mn values (2.02–2.93). In contrast...
