Abstract The reaction of the derivatives of 3-phenyl-3-chloro-2-oxopropionic acid with the trivalent phosphorus compounds has been studied. The esterification or amidation of this acid have been shown to influence the course of reaction with Ph3P. In the reaction with esters enolphosphonium salts are produced, ketophosphonium salts are obtained when amides are involved. Properties of these compounds have also been studied in the Wittig reaction. 3-(α-chlorobenzyl)-2-oxoquinoxaline which reacted with trialkyl phosphates (Arbuzov reaction) has been synthesized. These phosphonates are obtained in nearly quantitative yields, in alkaline conditions (Horner-Emmons reaction) they react smoothly with aromatic aldehydes to give the substituted vinylyuinoxalines. 相似文献

Binary cooligomers of C7 and C10 α-olefins with 2-propenylphenol were synthesized in the presence of a complex catalyst based on aluminum chloride, toluene, and ethyl chloride (1:3.0:0.6 mol). Tests of the cooligomers as antimicrobial additives to I-12A oil showed that, in concentrations of 0.25 and 0.5%, they inhibit fungal growth, being superior to 8-hydroxyquinoline (reference) in the efficiency of action. 相似文献

Polyconjugated oligomers containing aromatic links with hydroxyl and amino functional groups were synthesized by oxidative polycondensation of 4-aminophenol. They exhibit solubility and fusibility, heat resistant, paramagnetic and semiconductor properties, and also high reactivity in reactions characteristic for aromatic hydroxyl groups. These oligomers were used as supplements to industrial polymers. Composite materials were obtained including a rubber with high physico-mechanical, thermal, and electrical properties. 相似文献

A technology has been developed for the preparation of thin films of the Bi2Te2.7Se0.3 solid solution through the thermal evaporation in a vacuum using the “hot-wall” method. The high quality of the thin films thus prepared has been confirmed by the X-ray diffraction and Raman scattering data. The electron transport has been investigated over wide ranges of temperatures (1.4–300 K) and magnetic fields (up to 8 T). It has been assumed that the observed weak antilocalization is associated with the dominant contribution from the surface states of a topological insulator. The dephasing length has been estimated. 相似文献

采用普通溶液法合成了配合物[Zn(eiqnthz)_2]·DMF(1)和[Zn3(piqnthz)_2Cl_2]·2H_2O(2)(Heiqnthz=N,N′-乙酰异喹啉甲酰肼,H2piqnthz=N,N′-丙酰异喹啉甲酰肼)。通过X射线单晶衍射分析、X射线粉末衍射分析、红外光谱分析、热重分析以及荧光光谱分析等分析方法对2个配合物进行结构测定和性质表征。结构分析表明配合物1是单核结构,单斜晶系,空间群为C2/c,锌离子周围有4个氮原子和2个氧原子与之配位,形成一个畸变的N4O2八面体构型。配合物2属于单斜晶系,C2/c空间群,三核结构。中心原子Zn(1)、Zn(2)、Zn(3)均为5配位,Zn(1)、Zn(3)位于分子两端并且是变形四角锥配位构型,Zn(2)位于中间形成三角双锥配位构型,整体呈V字型。荧光分析表明Heiqnthz、H2piqnthz与锌(Ⅱ)离子配位后其荧光都发生较大的红移。 相似文献
