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).
