    日期:1996.9
    The reaction of salicylaldehydes 5 with phosphonoacetates 6 gives the coumarin-3-phosphonates 7 and the 1,2-benzoxaphosphorine-3-carboxylates 8 in yields and 7:8 ratios depending on the reaction conditions. A mechanistic explanation is given for the stereoselectivity of these reactions. Irradiation of compounds 8 or direct exposure to sunlight causes their head-to-tail dimerization, giving the dimers

    3-phosphonocoumarins were performed, and the effect of the substituents in the aryl moiety was evaluated. The structures possessing promising fluorescent properties were successfully synthesized via Suzuki and Sonogashira cross-coupling. The synthetic protocol was also applied for the phosphorous chemoisomer of 3-phosphonocoumarin, 1,2-benzoxaphosphorin, and their carboxylate analogues. The optical properties of the

  • Substituted Esters of Coumarin-3-phosphonic Acid—Linear-Polarized IR-Spectroscopic Elucidation
    作者:Rositca D. Nikolova、Sonya Zareva、Anka G. Bojilova、Tsonko Kolev、Bojidarka Koleva
    DOI:10.1080/10426500802049837
    日期:2008.11.7
    Correlation between the structure and IR-spectroscopic properties of two halogen and one amino substituted esters of coumarin-3-phosphonic acid has been studied by means of linear-polarized IR-spectroscopy of oriented colloid suspensions in nematic host. The influence of the ester group on the peak positions of the IR-characteristic bands of these derivatives and in particular, on phosphorus group is investigated by a comparison with the data for corresponding coumarin-3-phosphonic acids. Theoretical quantum chemical DFT calculations (B3LYP/6-311++G**) are carried out, thus supporting the experimental assignment of the IR-bands and predicting the electronic structure of all of the compounds studied.
