  • Thermally induced structural transformations of linear coordination polymers based on aluminum tris(diorganophosphates)

    Al[O2P(OR)2]3 proceeds either through β-elimination of olefin (for compounds with C2–C8 aliphatic ligands), or a homolytic cleavage of the P–OR bond (for methyl and phenyl derivatives); both processes are accompanied by condensation of the newly formed POH groups and liberation of water. Powder XRD, FTIR and SEM analyses of the solid residues indicate that thermolysis of Al[O2P(OR)2]3 accompanied by
    由通式为catena -Al [O 2 P(OR)2 ] 3的线性三(二有机磷酸铝)铝链组成的无机有机杂化聚合物的热转变(其中R = C 1 –C 8烷基或苯基部分)已通过DSC,粉末XRD,TGA和TG-QMS以及光谱学进行了研究。DSC和XRD表明,它们中的大多数由于其有机取代基的构象变化而在-100至200℃之间经历了固态的可逆结构转变。然而,仅在带有长的2-乙基己基的衍生物的情况下才发生刚性聚合物链的平移位移,该衍生物在约140℃下变为液体。所研究的聚合物的热分解过程在200至265°C之间开始,这取决于装饰其铝磷酸盐核心的有机取代基R的类型。TGA结合质谱分析所产生的气态产物表明Al [O 2 P(OR)2 ]的热分解3通过烯烃的β-消除(对于具有C 2 -C 8脂族配体的化合物)或P-OR键的均相裂解(对于甲基和苯基衍生物)进行;这两个过程都伴随着新形成的POH基团的缩合和水的

    Abstract : The reactions of trimethyl phosphite were investigated with a series of nucleophiles. Products, branching ratios, and reaction rate constants are reported. Reactions generally proceed through an ion-dipole complex (Z-. (CH3O) 3P), to a phosphoranide anion intermediate, (CH3O)3PZ-), to displacement of methoxide to form a new ion-dipole complex (CH3O-(CH3O)2PZ). If an additional acidic hydrogen
