摘要:设计并合成了基于分子内电荷转移(tict)的双探针双氰基乙烯基-9-苯基蒽(dpa),用于检测肼(n2H4),且检出限非常好(lod,7.85 Nm(0.25 Ppb)).在与肼相互作用时,吸电子的双氰基乙烯基的末端官能改变为给电子的氨基/ Hydr官能.因此,探针的光物理性质的显着变化归因于电荷传播方向的变化.带有肼的探针在介质中显示出比例荧光"开启"响应以及肉眼敏感的颜色变化.表面形态学研究(sem和tem)分别表明了探针dpa和衍生物dpa-Hdz的非晶性和晶体性质.探针的导电行为在与肼相互作用时降低,这是因为基质的无定形性降低并且相对更刚性的晶体结构增加.此外,该探针还用于检测溶液中和试纸条上的肼蒸气,并具有非常好的肉眼敏感响应.

标题 :Synthesis of aryl ethers
发明人：BUCHWALD STEPHEN L; WOLFE JOHN P; PALUCKI MICHAEL
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:A method for preparing an aryl ether compound is provided in which an alcohol is reacted with an aromatic compound in the presence of a base, and a transition metal catalyst selected from the group consisting of platinum and nickel to form an aryl ether. The aromatic compound comprises an activated substituent, X, said activated substituent being a moiety such that its conjugate acid HX has a pKa of less than 5.0. The catalyst is preferably a soluble palladium complex in the presence of supporting ligands.

权利人:UNIV CINCINNATI
摘要:The present invention is directed to a method and apparatus for simultaneously implementing mechanochemical and electrochemical synthesis conditions. With respect to the method, the method may be configured to improve one or more reaction metric such as increasing product yield, reducing organic solvent consumption, reducing the reaction time, reducing the amount of, or completely eliminating, at least one toxic reagent or solvent, or enabling electrochemical synthesis of the chemical product without complete solubility of the organic substrate in the organic solvent. With respect to the apparatus, the apparatus is configured to define a reaction area between an anode and cathode that can be mechanochemically agitated to improve synthesis without disrupting the electrochemical reaction.
