    Synthesis, Photopolymerization, and Adhesive Properties of Hydrolytically Stable Phosphonic Acid-Containing (Meth)acrylamides
    (WILEY-BLACKWELL, 2014) TÜRKER, ŞEBNEM BEGÜM; Altin, Ayse; Akgun, Burcin; Bilgici, Zeynep Sarayli; Turker, Sebnem Begum; Avci, Duygu
    Three novel dental monomers containing phosphonic acid groups (1a and 2a, based on diethyl amino(phenyl)methylphosphonate and 3a based on diethyl 1-aminoheptylphosphonate) were synthesized in two steps: the reaction of -aminophosphonates with acryloyl chloride (for monomers 1a and 3a) or methacryloyl chloride (for 2a) to give monomers with phosphonate groups, and the hydrolysis of phosphonate groups by using trimethyl silylbromide. Their (and the intermediates') structures were confirmed by FTIR, H-1, C-13, and P-31 NMR spectroscopy. All the monomers dissolve well in water (1

    Novel Bisphosphonated Methacrylates: Synthesis, Polymerizations, and Interactions with Hydroxyapatite
    (WILEY-V C H VERLAG GMBH, 2013) TÜRKER, ŞEBNEM BEGÜM; Bilgici, Zeynep Sarayli; Turker, Sebnem Begum; Avci, Duygu
    Five novel methacrylates containing either bisphosphonate (1 and 2), bisphosphonic acid (3), carboxylic acid (4), or both bisphosphonic andcarboxylic acid together (5), are synthesized. The monomers 1 and 2 are synthesized by the reactions of tetraethyl 1-hydroxyethane-1,1-diyldiphosphonate with ethyl -bromomethacrylate and tert-butyl -bromomethacrylate; the same procedure fails with tetraethyl hydroxy(phenyl)methylenediphosphonate. 1 is converted to 3 by hydrolysis with trimethylsilyl bromide (TMSBr), and 2 is converted to 4 by hydrolysis with trifluoroacetic acid (TFA). Monomer 5 is obtained by hydrolysis of 2 first with TMSBr and then with TFA. The hydrolytic stability, the properties of the copolymerizations with commercial dental monomers, and HAP interactions make these monomers promising candidates for dental adhesives. [GRAPHICS] .
