Organic compounds having carbon bonded to bromine are called organic bromides. 90-59-5, formula is C7H4Br2O2, Name is 3,5-Dibromo-2-hydroxybenzaldehyde. Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. COA of Formula: C7H4Br2O2.
Fok, Emily Y.;Show, Veronica L.;Johnson, Adam R. research published 《 Intramolecular hydroamination of trisubstituted aminoallenes catalyzed by titanium complexes of diaryl substituted tridentate imine-diols》, the research content is summarized as follows. The authors’ laboratory has developed catalysts based on earth abundant Ti for asym. reactions including intramol. hydroamination. Previously, Ti complexes of imine diol ligands showed improved enantioselectivity relative to complexes with bidentate amino alc. ligands. As the catalyst with the highest selectivity had di-tert-Bu substitution, the authors sought to increase the steric protection by preparing three new ligands with diaryl substitution. These ligands were readily prepared in two steps: 1st, synthesis of diaryl substituted salicylaldehydes by a Suzuki coupling and 2nd, a Schiff base condensation with a chiral amino alc. After characterizing the ligands, in situ hydroamination/cyclization with 6-methyl-hepta-4,5-dienylamine was carried out at 105-135° to give exclusively 2-(2-methyl-propenyl)-pyrrolidine with enantioselectivity up to 22%ee. Unexpected dimerization of the catalyst resulted in reduced activity, so the reaction required a catalyst loading of 10-20%.
90-59-5, 3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes.
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
