Lewis basesThe reaction of Dm (D = Me2SiO, m = 3–6) with silver hexafluoroantimonate in liquid SO2 affords a mixture of AgDnSbF6 (n = 6–8) complexes. Upon the addition of CH3CN, Ag+-directed ring transformations are effected, which allows for the isolation of neat Dn (n = 6–...

An enhanced concentration of surface MoO 3 species in tetrahedral coordination coupled with the presence of weak Lewis acid sites appear to be the main reason why MoO 3 -SiO 2 (SG) catalysts are superior to the MoO 3 -SiO 2 (I) system....
Li2SiO3Lewis acidLi-ion batteryA facile one-pot hydrothermal strategy is applied to prepare Co and F co-doped SnO2 (Co-F/SnO2) nanoparticles, which exhibits a unique rice-shaped self-similar structure. Compared with the pristine and Co-doped counterparts (SnO2 and Co/SnO2), Co-F/SnO2 ...
The crystal structure of 2 reveals a pseudo-square-pyramidal structure that can be viewed as a distorted tetrahedron with the W-H and W-C bonds occupying one site. The addition of H_2 (or D_2) to 1 proceeds similarly to afford (silox)_2(~tBuN=)WH_2 (3), and the addition of H...
Firstly, Ni was loaded onto ordered mesoporous alumina (OMA), SBA-15 and 纬-Al_2O_3 as the supports. By comparing the catalytic performance, the role of the pore structure and Lewis acid were elucidated. Our results indicated that hydrodeoxygenation of dibenzofuran with onl...
