Heterocyclic Building Block-benzofuran

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C9H8O, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 4265-25-2, Name is 2-Methylbenzofuran, molecular formula is C9H8O

We herein report a mild method for the preparation of dihydrobenzofurans through hydrothermal catalytic tandem Claisen rearrangement-intramolecular hydroaryloxylation of allyl phenyl ethers. This reaction provides a new method for constructing dihydrobenzofurans, a process that is potentially applicable to natural product synthesis. SBA-15, TS-1, HZSM-5 were chosen as catalysts in a hydrothermal reaction medium between 200 and 320 C. HZSM-5 catalyst showed the highest catalytic activity, and the effects of molar ratio of allyl phenyl ether-water, time, pressure, temperature and catalyst on the Claisen hydroaryloxylation in hydrothermal condition were investigated. The latter two process variables had the greatest influence on the product yields and distribution. A series of allyl phenyl ether derivatives were also treated in hydrothermal condition with HZSM-5 catalyst to offer high yield of corresponding dihydrobenzofurans.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C10H8O3, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 24673-56-1, Name is 3-Methylbenzofuran-2-carboxylic acid, molecular formula is C10H8O3

Pd-catalyzed decarboxylative Heck coupling of aromatic carboxylic acids with various olefins is developed using O2 as the terminal oxidant. Enhancement of O2 pressure leads to improving reaction turnover in this transformation and allows significantly reducing catalyst loading for efficient conversion of electron-rich benzoic acids. A Pd catalyst supported by a carbene ligand enables using electron-deficient benzoic acids as coupling partners.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Synthetic Route of 1563-38-8, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.1563-38-8, Name is 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol, molecular formula is C10H12O2. In a article，once mentioned of 1563-38-8

An area of shore on Laysan Island in the Hawaiian Islands National Wildlife Refuge has been observed over the last 10 years to cause mortality to several species of birds, crabs, and insects which come into contact with the sand. Previous analysis of two composite samples from 1993 and 1997 indicated contamination of carbofuran in the sand at levels in the low mug/g range. In November of 1997, and July and October of 1998, 129 additional samples were collected in order to define the extent of the carbofuran contamination. Sand samples were extracted with acetone in a pressurized fluid extractor and analyzed by GC-MS. Localized contamination was present at 1,639 mug/g of carbofuran and over 8,832 mug/g of its primary breakdown product, carbofuran-7-phenol. In addition to carbofuran-7-phenol, four other known transformation products were observed in sample extracts, including 3-hydroxy carbofuran, 3-keto carbofuran, 3-keto carbofuran phenol, and carbofuran diol. Two additional compounds which have not been previously reported as carbofuran breakdown products were also found. Spectra are presented and structures are proposed for these two compounds. The structure of one compound, carbofuran acetate, was confirmed by synthesis and GC/MS. To assess relative toxicity, Microtox bioassays were conducted for standards of carbofuran, 3-hydroxy carbofuran, and carbofuran-7-phenol, as well as for water extracts of native contaminated and clean sand. These assays supported the conclusion that the toxicity at the site can be explained by the presence of carbofuran and its products.
