In this proof-of-concept study, new monolithic columns were prepared by incorporating fumed silica nanoparticles (FNSPs) that are surface functionalized by covalent attachment of 1-[3-(trimethoxysilyl)propyl]urea moieties (i.e., carbamide-FSNPs). The prepared monolithic columns were successfully utilized in hydrophilic interaction liquid chromatography (HILIC) of small, relatively polar solutes. The organic polymer monolithic matrix was based on the in situ polymerization of glyceryl monomethacrylate (GMM) and ethylene glycol dimethacrylate (EDMA) yielding the poly(GMM-co-EDMA) monolith for the incorporation of carbamide-FSNPs. The poly(GMM-co-EDMA) monolithic column with incorporated carbamide-FSNPs which is referred to as carbamide-FSNPs-poly(GMM-co-EDMA) was investigated over a wide range of mobile phase compositions with polar acidic, weakly basic and neutral analytes including organic acids, food additives, vitamins, biological amines, nucleosides, nucleobases, dimethylformamide, formamide and thiourea. Improved peak shapes and better separations were achieved when anisocratic (i.e., gradient) elution conditions were used for the separation of nucleobases, nucleosides and vitamins. The run-to-run, day-to-day and column-to-column reproducibilities were satisfactory.

Traditional cross-coupling reactions show some disadvantages like the use of organohalides or the production of stoichiometric amounts of waste. The dehydrative homo- or heterocoupling of alcohols therefore arises as an interesting approach for a highly atom-economical formation of carbon-carbon bonds, since water is produced as the only by-product. We herein report a simple and direct, metal-free protocol for the synthesis of olefins by applying catalytic amounts of a sulfonic acid and triphenylphosphane under air. A variety of olefins could be synthesized from benzylic alcohols under relatively mild conditions. Additionally, dehydrative hydroarylation of benzylic alcohols with electron-rich arenes was possible by using only Bronsted acid under otherwise same reaction conditions. We could show that phosphane additives are essential to overcome oligomerization as main side reaction by the occupancy of the reactive carbocation intermediate.

A metal-free, oxidative coupling of phenols with various nucleophiles, including arenes, 1,3-diketones and other phenols, is reported. Cross-coupling is mediated by a sulfoxide which inverts the reactivity of the phenol partner. Crucially, the process shows high selectivity for cross-versus homo-coupling and allows efficient access to a variety of aromatic scaffolds including biaryls, benzofurans and, through an iterative procedure, aromatic oligomers.

Lignins from different tree barks, including Norway spruce (Picea abies), eucalyptus (Eucalyptus globulus), mimosa (Acacia dealbata) and blackwood acacia (A. melanoxylon), are thoroughly characterized. The lignin from E. globulus bark is found to be enriched in syringyl (S) units, with lower amounts of guaiacyl (G) and p-hydroxyphenyl (H) units (H/G/S ratio of 1:26:73), which produces a lignin that is highly enriched in beta-ether linkages (83 %), whereas those from the two Acacia barks have similar compositions (H/G/S ratio of approximate to 5:50:45), with a predominance of beta-ethers (73-75 %) and lower amounts of condensed carbon-carbon linkages; the lignin from A. dealbata bark also includes some resorcinol-related compounds, that appear to be incorporated or intimately associated to the polymer. The lignin from P. abies bark is enriched in G units, with lower amounts of H units (H/G ratio of 14:86); this lignin is thus depleted in beta-O-4 ‘ alkyl-aryl ether linkages (44 %) and enriched in condensed linkages. Interestingly, this lignin contains large amounts of hydroxystilbene glucosides that seem to be integrally incorporated into the lignin structure. This study indicates that lignins from tree barks can be seen as an interesting source of valuable phenolic compounds. Moreover, this study is useful for tailoring conversion technologies for bark deconstruction and valorization.

Here, we explore the GO-catalyzed cross-dehydrogenative coupling of oxindoles with arenes and thiophenols for the rapid synthesis of 3-aryloxindoles and 3-sulfenylated oxindoles. Control experiments and small-molecule mimicking studies reveal that the acidic nature and quinone-type functionalities of GO are synergistically utilized for the coupling reaction. The reaction proceeds under simple and mild reaction conditions, exhibits good functional group tolerance, and can be easily scaled up to the gram level.

N-Aryl amides are an important class of compounds in pharmaceutical and agrochemical chemistry. Rapid and low-cost synthesis of N-aryl amides remains in high demand. Herein, we disclose an operationally simple process to access N-aryl amides directly from readily available nitroarenes and carboxylic acids as coupling substrates. This method involves the in situ activation of carboxylic acids to acyloxyphosphonium salt for one-pot amidation, without the need for isolation of the corresponding synthetic intermediates. Furthermore, the ease of preparation and workup allow the quick and efficient synthesis of a wide range of N-aryl amides, including several amide-based druglike and agrochemical molecules.

We synthesized two kinds of monocarbamothioates TZO(R) containing a thiazolidin-2-one (TZO) skeleton and TZD(R) containing a thiazolidine-2,4-dione (TZD) skeleton. In the reaction of TZO(R) and phenoxypropyrenesulfide (PPS) using tetrabutylammonium chloride (TBAC) as a catalyst in 1-methyl-2-pyrrolidinone at 60 degrees C, anionic ring-opening polymerization of PPS proceeded to give the corresponding linear polysulfides, polyPPS, with M-n = 75 860-206 700 (M-w/M-n = 1.54-1.73) in high yield. In contrast, in the reaction of TZD(R) and PPS, the continuous insertion reaction of PPS into TZD(R), i.e., living ring-expansion polymerization, occurred to afford cyclic polysulfides TZD(R)-c-poly(PPS)(n) with M-n = 1870-33 420 (M-w/M-n = 1.07-1.26) in high yield. The ring size could be controlled by the feed ratio of TZD(R)/PPS in the range of 1/5-1/100.

A copper/silver co-catalyzed cross-dehydrogenative coupling reaction is developed to achieve exclusively remote C5-H coupling of 8-aminoquinoline amides with the methylenic sp (3) C-H bond of 1,3-dicarbonyl compounds. This protocol provides a highly regioselective synthetic route for the functionalization of 8-aminoquinoline amides at C5 under mild conditions.
