Abstract Engineering the dropwise condensation of water on surfaces is critical in a wide range applications from thermal management (e.g. heat pipes, chip cooling etc.) to harvesting technologies. Surfaces that enable both efficient droplet nucleation and self‐removal (i.e. departure) are essential accomplish successful condensation. However it extremely challenging design such surfaces. This because requires wettable surface while departure necessitates super‐hydrophobic surface. Here we...
A novel radical phosphinylation of α,α-diaryl allylic alcohols with arylphosphine oxides was described for the direct preparation α-aryl-β-phosphinylated carbonyl ketones in medium to good yields via 1,2-aryl migration. In this reaction, formation new C(Ar)–C(sp3) and C(sp3)–P bonds observed.
A metal-free method for direct C(sp3)–H bond functionalization of simple ethers with α,α-diaryl allylic alcohols is described. The established protocol provides facile access to α-aryl-β-oxyalkylated carbonyl ketones via radical addition and a 1,2-aryl migration cascade process. An application the product has been demonstrated in synthesis serotonin antagonist.
Abstract A metal‐free direct alkylation of simple carbonyl compounds (ketones, esters, and amides) with α,α‐diaryl allylic alcohols is described. The protocol provides facile access to highly functionalized dicarbonyl ketones by a radical addition/1,2‐aryl migration cascade. regioselectivity the reaction was precisely controlled nature compound.
Abstract A metal‐free tandem procedure by using a sulfonylation reaction of aryl allylic alcohols followed an iodobenzenediacetate (PIDA)‐promoted oxidative functionalization has been established. Allylic sulfones, γ‐ketosulfones, and triflyl have constructed in single operation. The methodology incorporates the sulfonyl (both triflyl) functionality with simple work‐up procedure.
Direct oxidative C(sp<sup>3</sup>)–H functionalization of acetonitrile and alkanes with α,α-diaryl allylic alcohols has been developed.
A Cu-mediated/catalyzed oxycyanomethylation reaction of olefinic amides with acetonitrile was developed for the synthesis important benzoxazine derivatives.
An analytical numerical model to optimize the shape of concave surface texture for achievement low friction in reciprocating sliding motion has been developed. The uses: (i) average Reynolds equation evaluate coefficient and (ii) genetic algorithm (GA) obtain several preferable shapes. Analysis distribution contour maps hydrodynamic pressure gives possible mechanisms involved. Moreover, experimental comparisons tribological performances between optimized circular textures were conducted...
A Cu-mediated/catalyzed selective oxidative dual C–H bond cleavage of an arene and alkylnitrile or acetone is reported. This method provides alternative for designing new pharmaceutical frameworks photoelectronic devices.
Purpose – The main purpose of this paper is to understand and model the hydrodynamic influence surface textures on journal bearings. Design/methodology/approach In model, a rectangular array circle dimples used modify film thickness expression. full cavitation regions, classical Reynolds equation boundary condition are as governing equations, respectively. By setting high load bearing capacity optimal goal, tribological characteristics studied get distribution parameters textures. Findings...
