4-Bromo-4'-hidroxibifenilo, 98 %, Thermo Scientific Chemicals
Descripción
A biphenyl starting material. 4-Bromo-(1,1-biphenyl)-4-ol is a useful intermediate. Vinylation of 4-bromo-4-hydroxybiphenyl and ethyl acrylate using Pd (OAc) 2/PPh 3 catalyst was studied. Ethyl 4-(4-hydroxyphenyl) cinnamate was formed as the vinylation product, while, 4-hydroxybiphenyl and ethyl cinnamate were formed as side products. Preparation of 4-cyano-4'-hydroxybiphenyl This was prepared from 4-bromo-4'-benzenesulphonyloxybiphenyl by first hydrolysing it to 4-bromo-4-hydroxybiphenyl using sodium hydroxide dissolved in a mixture of water and dioxan. The syntheses of the Nanocomposite dendrimers based on cyclic phosphazene cores: Amorphous materials, were accomplished by following a modified literature procedure by reacting phosphonitrilic chloride trimer with 4-bromophenol or 4-bromo-4-hydroxybiphenyl, respectively, in the presence of K 2 CO 3 in tetrahydrofuran (THF).

Un material de partida de bifenilo. 4′El -bromo-(1,1′-bifenil)-4-ol es un intermedio útil. Se estudió la vinilación de 4-bromo-4′-hidroxibifenilo y acrilato de etilo utilizando el catalizador Pd (OAc) 2/PPh 3 El cinnamato de etilo 4-(4′-hidroxifenilo) se formó como producto de vinilación, mientras que el 4-hidroxibifenilo y el cinnamato de etilo se formaron como productos secundarios. Preparación de 4-ciano-4′-hidroxibifenilo se preparó a partir de 4-bromo-4′-bencenosulfoniloxibifenilo por primera hidrolizando a 4-bromo-4-hidroxibifenilo mediante hidróxido sódico disuelto en una mezcla de agua y dioxano. Las síntesis de los dendrímeros nanocompuestos basados en núcleos de fosfaceno cíclico: Los materiales amorfos, se realizaron siguiendo un procedimiento de literatura modificado, reaccionando el trímero de cloruro fosfonitrílico con 4-bromofenol o 4-bromo-4′-hidroxibifenilo, respectivamente, en presencia de K 2 CO 3 en tetrahidrofurano (THF).
