The aim of this paper is to improve the conversion of sugarcane bagasse to pyrolytic sugar levoglucosan through its pretreatment with acetic acid (10 wt.%) at 90 C for 10 min under 200 rpm. Then, acid treated biomass was rinsed with deionized water to a neutral pH and dried in a vacuum oven at 70 C up to constant weight. After acid treatment, the samples were subjected to fast pyrolysis in a Py-GC/MS. Thus, the impact of the acetic acid on the levoglucosan yield as well as other pyrolytic compounds released during pyrolysis process at different temperatures (from 350 to 600 C) is reported. The best results respect to levoglucosan yield were attained when pyrolysis was performed at 400 C resulting in around nine folds levoglucosan production from sugarcane bagasse after biomass treatment with acid compared to the control (untreated biomass samples) while the yield of some undesirable lignin derived compounds decreases in acid washed samples. The effect observed is due to the removal of the catalytic activity of alkali and alkaline earth metals. The attained results are very attractive because this pyrolytic sugar exhibits great potential as renewable feedstock for biofuels production and other bioproducts.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 4971-56-6, and how the biochemistry of the body works.Application of 4971-56-6

Little is known about bromine trifluoride in organic chemistry. Under the right conditions, it can be a useful tool and generate a new and unprecedented chemistry. Thus, when reacted with oxime methyl ethers of alpha-ketoesters, BrF3 was able to convert the oxime group into a CF2 group and through a new type of rearrangement cause a shift of the carboxylate group to the nitrogen atom. The novel structure of the alpha,alpha-difluorocarbamate was also proven by 15N NMR as demonstrated for compounds 3, 8, 9, 12, 15, and 18. Another novel “double rearrangement” was observed during the formation of 19. Dynamic 19F NMR experiments indicate a high nitrogen inversion-rotation (NIR) barrier for these novel carbamates of about 12.5 kcal/mol.

Cyclopentenones are synthetically versatile structures, and their straightforward construction from alkynone substrates by employing synthetically streamlining C-H insertion is conceptually appealing and of high synthetic potential. But, its implementation is very limited. Herein we report a Au-catalyzed version, which affords 2-bromocyclopent-2-en-1-ones with a broad scope and synthetically desirable diastereoselectivities. The proposed key intermediate capable of the observed insertion into unactivated C-H bonds is a fully functionalized gold vinylidene, which is generated via a novel intermolecular strategy. This flexible access of likely gold vinylidenes opens various opportunities to explore their versatile reactivities.

Mono-functional catalytic materials are used for many types of chemical transformations, but are tedious for delivering products from multiple-step reactions required for the valorization of biomass. An emerging trend is to integrate catalytic transformations, reaction engineering and product separation into a single operation, wherein catalyst design is considered as the key approach to develop efficient, low energy and environmentally-friendly reaction systems. Bifunctional solid catalysts open a door for carrying out domino/cascade- and tandem/sequential-type reactions in a single pot, for which the number of isolation or purification steps can be lessened or eliminated so that removal of unwanted by-products becomes unnecessary. This review introduces bifunctional materials used in one-pot multiple transformations of biomass into biofuels and related chemicals. Emphasis is placed on the assessment of the bifunctionality of catalytic materials, including Bronsted-Lewis acid, acid-base, and metal particles-acid or base bifunctional catalysts with some discussion being on combined catalytic systems with electrochemical, chemo-enzymatic and photochemical methods. Plausible reaction mechanisms for key pathways are shown. Relevant auxiliaries to boost catalytic activity and product selectivity, such as reaction media, heating modes and morphological properties of the catalytic materials are analyzed. Use of appropriate bifunctional catalytic materials provides many opportunities for design of highly efficient reaction systems and simplified processing for producing biofuels and chemicals from lignocellulosic biomass.
