Wen, Chang;Wu, Chuan;Luo, Ruiqiang;Li, Qinghan;Chen, Feng research published 《 Highly Efficient Synthesis of 2-Substituted Benzo[ b ]furan Derivatives from the Cross-Coupling Reactions of 2-Halobenzo[ b ]furans with Organoalane Reagents》, the research content is summarized as follows. A highly efficient and simple route for the synthesis of benzo[ b]furans was developed by palladium-catalyzed cross-coupling reaction of 2-halobenzo[ b]furans with aryl, alkynyl, and alkylaluminum reagents. Various 2-aryl-, 2-alkynyl-, and 2-alkyl benzo[ b]furans was obtained in 23-97% isolated yields using 2-3 mol% PdCl 2/4-6 mol% XantPhos as the catalyst under mild reaction conditions. The aryls beared electron-donating or electron-withdrawing groups in 2-halobenzo[ b]furans gave products in 40-97% isolated yields. In addition, aluminum reagents containing thienyl, furanyl, trimethylsilanyl, and benzyl groups worked efficiently with 2-halobenzo[ b]furans as well, and three bioactive mols. with benzo[ b]furans skeleton were synthesized. Furthermore, the broad substrates scope and the typical maintenance of vigorous efficiency on gram scale made this protocol a potentially practical method to synthesize benzo[ b]furans. On the basis of the exptl. results, a possible catalytic cycle was proposed.

3,5-Dibromosalicylaldehyde, also known as 3,5-Dibromosalicylaldehyde, is a useful research compound. Its molecular formula is C7H4Br2O2 and its molecular weight is 279.91 g/mol. The purity is usually 95%.
3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes. 3,5-Dibromosalicylaldehyde can be used in the synthesis of Schiff base and can be used as reactant for synthesis of Schiff base ligands which forms mononuclear complexes with copper(II), nickel(II), zinc(II) and cobalt(II).
3,5-Dibromosalicylaldehyde is a copper complex that has been synthesized from 3,5-dibromosalicylaldehyde and copper chloride. FTIR spectroscopy revealed that the coordination geometry of the copper complex is octahedral with two nitrogen atoms in the equatorial plane. The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., COA of Formula: C7H4Br2O2
