Preparation and mechanism research on hydrophobic coupling modification of HTV silicone rubber

Frontiers in Materials
Neat high-temperature vulcanized silicone rubber (HTV SR) showed bad hydrophobicity due to the existence of a large number of inorganic reinforcing fillers on its surface, which affected its security application in outdoor insulation systems.

Rhodium-catalyzed homo-coupling reaction of aryl Grignard reagents and its application for the synthesis of an integrin inhibitor

Beilstein Journal of Organic Chemistry
A novel Rh-catalyzed one-pot homo-coupling reaction of aryl Grignard reagents was achieved. The reaction with bromobenzenes having an electron-donating group or a halogen substituent gave the corresponding homo-coupling products in good yields, although ...

A Reaction Kinetic Model for Vacuum-Field Catalysis Based on Vibrational Light-Matter Coupling

, 2019
Since conventional catalysts are materials-based, they are effective only for particular chemical reactions. Recent studies suggest that vacuum-field catalysis (or cavity catalysis) based on vibrational light-matter coupling can boost reactions without ...

New sulfenate sources for double pallado-catalyzed cross-coupling reaction: application in symmetrical biarylsulfoxides synthesis, and evidence of TADF properties.

Tetrahydro-4H-thiopyran-4-one 1-oxide 1 and sulfinyl-di-tert-butylpropionate 2 were reported as sources of bis-sulfenate anion and applied in a double pallado-catalyzed cross-coupling reaction for the synthesis of symmetrical biarylsulfoxides, tolerating

Synthesis of gem-Difluoroalkenes via Nickel-Catalyzed Allylic Defluorinative Reductive Cross-Coupling

, 2018
In this protocol, we report an allylic defluorinative reductive cross-coupling reaction for C–C bond formation. Under the Ni-catalysis the challenging C­(sp3)–F bond cleavage of trifluoromethyl-substituted alkenes was achieved with easily accessible ...
