Disclosed is a novel group of compounds having a general structure of anthracene body substituted with at least one thiophenyl group, which can be further substituted with various substituent groups. These new compounds are generally compatible with organic electroluminescence. Also disclosed are organic electroluminescent devices and method of making the same. The organic electroluminescent devices include at least one of the compounds in various layers thereof. Organic electroluminescent devices employing the new compounds in their light-emitting layers show outstanding stability.

A regioselective anti-hydrochlorination of unactivated alkynes is reported. The reaction utilizes in situ generated HCl as the source of both the Cl- and H+ and is catalyzed by palladium(II) acetate, with loadings as low as 25 ppm. Removable picolinamide and 8-aminoquinoline bidentate directing groups are used to control the regioselectivity of the chloropalladation step and stabilize the resulting
报道了未活化炔烃的区域选择性抗氢氯化作用。该反应利用原位生成的 HCl 作为 Cl- 和 H+ 的来源,并由乙酸钯 (II) 催化,负载量低至 25 ppm。可去除的吡啶甲酰胺和 8-氨基喹啉二齿导向基团用于控制氯钯化步骤的区域选择性,并稳定所得的链烯基钯 (II) 中间体,用于随后的原脱钯反应。该方法提供了以优异的产率和高区域选择性获得广泛的取代链烯基氯的途径。这种转化的产物通过 Stille 偶联成功衍生为多种三取代烯烃产物。进行了反应进程动力学分析,揭示了该催化过程的可能机制。

日期:——
good yields by successive solvolysis of propargyl bromide in liquid ammonia, metalation of the dissolved amine with sodamide, and hydrolysis after complete removal of the ammonia by evaporation. Somehomologues, RC≡CCH 2 NH 2 , have been obtained in fair yields by addition of alkyl bromides to the solution of the sodium derivative of 1-amino-2-propyne.
