This sequence supports our earlier predictions concerning the effects of the electronic structure of the metal atom on the acidity of covalent halides. Adduct formation between SnCl4 and a serIes of unhindered anilines in dioxan solution is related to the protonation of the bases by the equation ...
(Et2O) was identified as the most efficient reaction medium in terms of enantioselectivity (Supplementary Table 1). Next, several chiral disulfonimide catalysts1a–1fwere screened to elucidate the relationship between the catalyst’s structure and the reaction outcome (Fig. 2). The performance of ...

The complex [Rh(CO)Cl{Me 2 PC(Me)=C(Me)BMe 2 } 2 ] (5) has been prepared again in order to prove its structure with weak bonding interactions between the basic rhodium centre and the Lewisacidic Me 2 B group of the donor/acceptor ligand Me 2 PC(Me)=C(Me)
Tungsten nitride films were deposited on heated substrates by the reaction of vapors of tungsten bis(alkylimide)bis(dialkylamide) and a Lewis base or a hydrogen plasma. For example, vapors of tungsten bis(tert-butylimide)bis(dimethylamide) and ammonia gas supplied in alternate doses to surfaces...
of 48.7:15.2:36.1 to form a Lewis-basic bromide. After treatment, the LB-Ti3C2Txshows an obvious expanded layer structure (Fig.1d), in which the interlayer spacing increases to 14.7 Å (6.01° in XRD, Fig.1e). Such a large interlayer spacing is superior to that of many reported...
wherein R11 and R12 are each independently, hydrocarbon C1-C20 and may be substituted at least once with a halide, hydroxyl, amine, amide, thiol, thioether, carboxylate, or a carbon structure of C1-C12 group which optionally may be substituted with any of the above preceding groups. 32. A...
