3-Hydroxyphthalide, C8H6O3, reacts with dibutyltin oxide to give bis{mu 3-oxo-(mu-2-formylbenzoato-O:O?)-(2-formylbenzoato-O) bis[dibutyltin(IV)]}, [Sn4(C4H9)8-(C8H 5O3)4(mu-O)2], in which the four Sn atoms are all five-coordinated to three O and two C atoms arranged at the corners of a distorted trigonal bipyramid. The equatorial Sn – mu3-O distances are in the range 2.039 (2)-2.048 (2) A and are significantly shorter than the axial Sn – mu3-O distances of 2.170 (3) and 2.182 (2) A. The Sn – Ocarboxylate bonds are all axial and have distances in the range 2.204 (3)-2.271 (3) A, which are inversely correlated with the respective C – O bond distances. The mean Sn – C distance is 2.136 (6) A. 3-Hydroxyphthalide undergoes ring opening to give the anion of 2-formylbenzoic acid which bonds to the Sn atoms. The structure of 3-hydroxyphthalide is stabilized by O -H…O hydrogen bonds [O…O = 2.766 (1) A] which link the molecules in a zigzag chain parallel to b.

A key intermediate was obtained as solid through filtration of the reaction mixture of saccharin, chloro(triphenyl)phosphonium chloride, and N, N -diisopropylethylamine (DIPEA) in chloroform. The soluble triphenylphosphine oxide went to filtrate as waste, while the solid was reacted with amines to afford N -sulfonylamidines. In total, 26 N -sulfonylamidine products were obtained in moderate to good overall yields.

New heteroaryl-substituted o-divinylbenzenes, 2,2?-(1,2- phenylenedivinylene)difuran (9), 2,2?-(1,2-phenylenedivinylene)bisbenzo[b] furan (10), and 2,2?-(1,2-phenylenedivinylene)bisnaphtho[2,1-b]furan (11), were prepared and irradiated at various concentrations; intramolecular photocycloaddition and intermolecular [2 + 2] two-fold photoaddition reactions took place to give bicyclo[3.2.1]octadiene derivatives 12-14 and cyclophane derivatives 15-17, respectively. Compound 11 was the most selective of these o-divinylbenzenes, which, owing to pi-pi intra- or intermolecular complexation, gave only the exo-bicyclo[3.2.1]octadiene derivative 14 at low concentrations, and only the cyclophane derivative 17 at high concentrations.

3199-61-9, Name is Ethyl benzofuran-2-carboxylate, belongs to benzofurans compound, is a common compound. Formula: C11H10O3In an article, once mentioned the new application about 3199-61-9.

The Roessing’s reaction of 4-substituted 2-acylphenoxyacetic acids give a mixture of benzofurans and 2-benzofurancarboxylic acids. The relative yields of benzofurans and 2-benzofurancarboxylic acids depend on the substituents on the benzene ring of the 2-acylphenoxyacetic acids. Electron-withdrawing substituents such as nitro groups favor the formation of 2-benzofurancarboxylic acids. On the other hand, the formation of benzofurans is favored by the steric hindrance of 2-acyl groups in the reaction of 2-acyl-4-nitrophenoxyacetic acids with anhydrous sodium acetate and acetic anhydride.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Computed Properties of C8H7NO2. Introducing a new discovery about 57319-65-0, Name is 6-Aminoisobenzofuran-1(3H)-one

A novel strategy for aromatic trifluoromethylation by converting aromatic amino group into CF3 group is reported herein. This method, which can be considered as trifluoromethylation variation of the classic Sandmeyer reaction, uses readily available aromatic amines as starting materials and is performed under mild conditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C8H7NO2, you can also check out more blogs about57319-65-0

o-Alkylbenzenecarboxylic acids are treated with a sodium bromate and sodium hydrogen sulfite reagent under a two-phase system using ethyl acetate as solvent, under mild conditions to give the corresponding cyclized phthalides in moderate to satisfactory yield. Intermediately the alpha-brominated alkylbenzenecarboxylic acids are formed by the in situ generated hypobromous acid. These alpha-brominated acids undergo an intramolecular nucleophilic substitution reaction to afford the corresponding gamma-lactones.
