Through research, I have a further understanding and discovery of 3-Methylbenzoic acid. Recommanded Product: 99-04-7

An eco-friendly and a simple ipso-nitration protocol for a series of aliphatic and (hetero)aromatic carboxylic acids using nitronium tetrafluoroborate, 1-hexyl-3,4,5-trimethyl-1H-imidazolium tetrafluoroborate and base is reported. While contrasted with recently known decarboxylative ipso-nitration strategies for the preparation of nitro compounds, this protocol does not require a toxic metal catalyst and harmful volatile organic solvents. Moreover, this method is perfect for a broad range of functional groups and affords exclusively the ipso-nitrated product in moderate to good yields. (C) 2019 Elsevier Ltd. All rights reserved.

According to the Food and Agriculture Organization (FAO), Iran is the largest pistachio (Pistacia vera) producer in the world. Nevertheless, pistachio by-products (PBs) contain a high level of phenolic and cellulose compounds, it can be used as a substrate for the preparation of solid acid catalysts. In this work, the novel pistachio hull-OxTiCl4 (-) (x) catalyst was synthesized via preparing pistachio hull, product of Kerman, as a support followed by treatment with titanium tetrachloride (TiCl4) and identified by Fourier transform infrared spectroscopy, field emission scanning electron microscopy (FE-SEM), X-ray diffraction spectroscopy (EDX), thermogravimetric analysis (TG), Brunauer-Emmett-Teller (BET) and X-ray powder diffraction (XRD). The size of the nano-pistachio hull-OxTiCl4 (-) (x) nanocatalyst was shown by a scanning electron microscope below 100 nm. The catalytic activity of the solid acid catalyst has been successfully examined in a one-pot, three-component condensation reaction of aromatic aldehydes, dimedone and kojic acid in refluxing ethanol to furnish dihydropyrano[3,2-b]chromendione derivatives. Consequently, pyran annulated heterocycles were obtained. The proposed approach has some advantages as excellent yields, mild reaction conditions, short reaction times, use of agricultural waste and eco-friendly.

Axially chiral atropisomeric compounds are widely applied in asymmetric catalysis and medicinal chemistry, and efficient methods for their synthesis are in high demand. This applies in particular to atropisomers derived from five-membered aromatic rings because their lower barrier for rotation among the biaryl axis limits their asymmetric synthesis. We report here an enantioselective C-H functionalization method using our chiral RhJasCp complex for the synthesis of the biaryl atropisomer types that can be accessed from three different five-membered-ring heterocycles.

A simple and efficient one-pot method has been developed for the synthesis of benzochromenes (4a-k) using V-CaHAp as a heterogeneous catalyst by the condensation of aldehydes, beta-naphthol and malononitrile in ethanol as solvent at room temperature for 20 min. The reaction, with this catalyst was carried out under mild reaction conditions with very good to excellent yields (89-98%). The material can be recycled very easily and reused for at least 6 runs without substantial loss in activity, which makes this methodology environmentally benign. We achieved a feasible and cost-effective synthesis by using non-toxic materials and minimal catalyst which is easy to handle. (C) 2015 The Authors.
