Desai, Deepak S.;Yadav, Ganapati D. research published 《 Solvent-free oxidative esterification of furfural to 2-methyl furoate using novel copper-exchanged tungstophosphoric acid supported on montmorillonite K-10 catalyst》, the research content is summarized as follows. The valorization of bio-based chems. using green processes plays a vital role in the up-gradation of biofuels that are useful to reduce the demand for fossil feedstock. Furfural is a promising renewable biomass-based platform chem., which can be catalyically transformed into many value-added chems. Oxidative esterification of furfural produces 2-Me furoate, which is used as flavor and fragrance in fine chem. industries. There lies a challenge to find a cheaper and efficient catalyst for one-pot oxidative esterification of furfural. Supported heteropolyacids (HPAs) are useful for many biomass transformation reactions owing to their strong Bronsted acidity as well as high surface area, which both help promote catalytic surface reaction. In the present work, we have synthesized Cu exchanged tungstophosphoric acid (TPA) with different supports, viz. SiO₂, ZrO₂, and montmorillonite K-10 clay (K10) which were prepared by incipient wetness impregnation. Oxidative esterification of furfural with Me alc. was investigated using the aforesaid catalysts and tert-Bu hydroperoxide (TBHP) as an oxidant. 20% weight/weight Cu substituted TPA (abbreviated as Cu-TK10) catalyst is green, stable, active, selective, reusable, and cheaper. It was observed that the higher acidic strength and good surface area are responsible for oxidative esterification of furfural and Me alc. with higher selectivity. In this work, 91% conversion with 100% selectivity was achieved in 5 h at 120°C using 1:3 molar ratio of furfural and TBHP with a catalyst loading of 0.01 g/cm³. The synthesized catalysts were analyzed by various characterization techniques such as SEM, XRD, FT-IR, BET surface area analyzer, and NH₃-TPD, before and after use. This is an interesting example of valorization of furfural.

Demonti, Luca;Saffon-Merceron, Nathalie;Mezailles, Nicolas;Nebra, Noel research published 《 Cross-Coupling through Ag(I)/Ag(III) Redox Manifold》, the research content is summarized as follows. Trifluoromethyl argentates(III) undergo reductive elimination with arylboronic acids, yielding trifluoromethylarenes. In ample variety of transformations, the presence of silver as an additive or co-catalyst is believed to be innocuous for the efficiency of the operating metal catalyst. Even though Ag additives are required often as coupling partners, oxidants or halide scavengers, its role as a catalytically competent species is widely neglected in cross-coupling reactions. Most likely, this is due to the erroneously assumed incapacity of Ag to undergo 2e^– redox steps. Definite proof is herein provided for the required elementary steps to accomplish the oxidative trifluoromethylation of arenes through Ag^I/Ag^III redox catalysis (i. e. CEL coupling), namely: (i) easy Ag^I/Ag^III 2e^– oxidation mediated by air; (ii) bpy/phen ligation to Ag^III; (iii) boron-to-Ag^III aryl transfer; and (iv) ulterior reductive elimination of benzotrifluorides from an [aryl-Ag^III-CF₃] fragment. More precisely, an ultimate entry and full characterization of organosilver(III) compounds [K]⁺[Ag^III(CF₃)₄]^– (K-1), [(bpy)Ag^III(CF₃)₃] (2) and [(phen)Ag^III(CF₃)₃] (3), is described. The utility of 3 in cross-coupling has been showcased unambiguously, and a large variety of arylboron compounds was trifluoromethylated via [Ag^III(aryl)(CF₃)₃]^– intermediates. This work breaks with old stereotypes and misconceptions regarding the inability of Ag to undergo cross-coupling by itself.

Thermal degradation was carried out to known if the addition of graphene causes any changes in the degradation processes of LE-PBMA/graphene 12 w%, and it was compared to that of pure LE-PBMA prepared by ATRP (atom transfer radical polymerization) method. When compared with those of PBMA prepared by free radical polymerization, the trend of depolymerization for LE-PBMA in the presence of graphene in the composite system decreased from 78% (by mol) up to 37% (by mol). The FT-IR, ¹H- ¹³C-NMR and GC-MS data showed that depolymerization corresponding to monomer (benzyl methacrylate) was the most important product trapped at CRF (cold ring fraction) in the thermal degradation of composite.
