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., Related Products of 90-59-5

Sundaresan, Sriram;Kuhne, Irina A.;Evesson, Colin;Harris, Michelle M.;Fitzpatrick, Anthony J.;Ahmed, Ahmed;Muller-Bunz, Helge;Morgan, Grace G. research published 《 Compressed Jahn-Teller octahedra and spin quintet-triplet switching in coordinatively elastic manganese(III) complexes》, the research content is summarized as follows. Complex assembly preferences and resultant spin state choice and Jahn-Teller distortion mode in twelve Mn(III) complexes of varying nuclearity with Schiff base chelate ligands of different sizes are compared. Mononuclear complexes [Mn(5-F-Sal2323)]OTf (1), [Mn(5-F-Sal2323)]ClO4 (2) and [Mn(5-F-Sal2323)]NO3, (3) with the 8-carbon R-Sal2323 chelate type show rare axial compression at room temperature and complexes (2) and (3) also show reversible thermal spin state switching from spin quintet to triplet states on cooling. The prevalence of atypical axial compression is further probed by single crystal diffraction studies on high spin mononuclear complexes (4)-(7) with the longer 9-carbon R-Sal2333 chelate series using [Mn(3-OEt-Sal2333)]BF4, (4) [Mn(3,5-diOMe-Sal2333)]BF4·0.5PrOH, (5), [Mn(5-F-Sal2333)]BPh4, (6) and [Mn(5-NO2-Sal2333)]BPh4, (7) as examples. Ring closure of both the 8-carbon R-Sal2323 and longer 9-carbon R-Sal2333 ligands was also observed yielding a ligand with a 6-membered ring in the mononuclear complex [Mn(3-OMe,5-NO2-Sal23336R)]·0.07MeOH·0.93MeCN (8) in contrast to a protonated 5-membered ring in the dimeric complex [Mn2(5-Cl-Sal2323H5R)2](ClO4)2·1.85EtOH·0.33MeCN, (9) with the R-Sal2323 chelate type. Finally comparison of the assembly modes of Mn(III) complexes of the 8-carbon R-Sal2323 and 9-carbon R-Sal2333 series with those of the shorter 7-carbon R-Sal2322 ligand series reveal that the mononuclear assembly mode is not favored with the smaller chelate. Instead three dimeric or cluster complexes with rearranged ligands were recovered in low yield. The structures of these complexes [Mn2(5-NO2-Sal23225R)2]·2BuOH, (10), [Mn2(3,5-diBr-Sal23225R)(3,5-diBr-Sal)3]·0.7EtOH·2.61MeCN, (11) and [Mn2Na(3-NO2,5-OMe-Sal23225R)]ClO4·0.5MeCN (12) are reported and compared with examples with the longer chain R-Sal2323 and R-Sal2333 chelate ligands.
