para-Selective Alkylation of Benzamides and Aromatic Ketones by Cooperative Nickel/Aluminum Catalysis

“…Unfortunately, styrene, cyclohexene, vinylboronate, and alkyl vinyl ether derivatives did not engage in such alkylation reactions (Table S1 of Supporting Information). Subsequently, we surveyed the scope of benzamides using vinylsilane 2g , as this should provide products with convertible silyl groups . Morpholino­(phenyl)­methanone ( 1b ), whose aminocarbonyl functionality can be readily transformed to ketones by nucleophilic carbonyl substitution reactions, afforded 3bg in excellent yield and para -selectivity.…”

Amine-functionalized SBA-15 in poly(styrene-b-butadiene-b-styrene) (SBS) yields permeable and selective nanostructured membranes for gas separation

“…fully extended towards the center of the pore, since the length of each gra in its extended conformation is 0.66 nm. This value is worked out from the bond lengths (C-C 0.153 nm, 97 C-N 0.147 nm, 97 C-Si 0.189 nm, 98 O-Si 0.163 nm 98 ) by assuming for simplicity that all bond angles are equal to 109.46 . However, such an extended conformation of the 3-aminopropyl group is not probable, and more than one layer of gras is expected (Fig.…”

Relay Palladium/Copper Catalysis Enabled Silylative [5 + 1] Benzannulation Using Terminal Alkynes as One-Carbon Units

“…Moreover, this reaction is highlighted by a regiospecific annulation with two bonds, C–C and CC, formation occurred on the same terminal sp-hybridized carbon atom via cleavage of two π-bonds and one C­(sp)–H bond, and a facile introduction of bioactive molecule skeletons into the resulting arylsilanes. Notably, arylsilanes are important common chemicals that widely constitute an important class of synthetic building blocks, ligands in synthesis, pharmacodynamic groups to modify drugs and bioactive molecules, and functional materials in industry. − …”
