Web4. apr 2024 · Herein, we describe an organocatalytic approach for straightforward acylation of C(sp3)–H bonds employing readily available aldehyde as “acyl source” involving dehydrogenative coupling of aldehydes with ether, amine, or benzylic C(sp3)–H bonds. The developed method affords a broad range of ketones under mild conditions. Web21. jan 2024 · In general, sp 3 bonded B and N atoms guarantee higher mechanical properties, and sp 2 bonded atoms ensure ductility and even conductivity, although all changes vary with spatial structure. Hex- (BN) 12 can be obtained from multilayer yne-BN, and BN nanosheets, nanotubes and nanoribbons under pressure. Introduction
