Metal- and Acid-Free, TBN-Mediated Direct C–H Nitration of Arenes
Publication date: Available online 18 January 2019Source: Journal of Saudi Chemical SocietyAuthor(s): Guangqiang Xu, Li Zhou, Chengdong Lv, Mo Xian, Qinggang WangAbstractA metal-free, acid-free, direct and eco-friendly nitration methodology has been developed. A tert-butyl nitrite efficiently promotes the direct C-H nitration of electron-rich arenes with good to excellent yields and regioselectivities. The practical utility of this protocol has been demonstrated in gram-scale nitration of crown ether and mono nitration of Sesamin. A plausible free radical mechanism is proposed based on detailed experimental observations.Gr...

UV-Induced Catalyst-Free Intramolecular Formal Heck Reaction
Publication date: Available online 31 December 2018Source: Journal of Saudi Chemical SocietyAuthor(s): Wangsheng Liu, Dongmei Ma, Hao Guo, Guangxin GuAbstractA catalyst-free intramolecular formal Heck reaction has been developed, affording 9-benzylidene-9H-fluorene derivatives under UV irradiation. This reaction probably proceeds via UV-induced homolytic cleavage of C-I bond, addition of the aryl radical to the alkene moiety, single electron oxidation of alkyl radical intermediate into carbocation species, and deprotonation.Graphical abstract (Source: Journal of Saudi Chemical Society)

Determination of chlorinated hydrocarbons in milk samples using sol-gel based polymer coated silica sorbent for stir-bar supported micro-solid-phase extraction coupled with gas chromatography mass-spectrometry
Publication date: Available online 7 December 2018Source: Journal of Saudi Chemical SocietyAuthor(s): Khalid AlhooshaniAbstractIn this work, sol-gel reaction chemistry was utilized to create 3-(trimethoxysilyl)propyl methacrylate-poly (propylene glycol) polymer coating on amorphous silica. The synthesized sorbent was characterized using energy dispersive X-ray spectrometry, field emission scanning electron microscopy, and thermogravimetric analysis. The sorbent was then used for membrane protected stir-bar supported micro-solid-phase extraction (SB-µ-SPE) of chlorinated hydrocarbons (CHCs) in milk samples and analyzed usi...

Mechanism and kinetics of uric acid adsorption on nanosized hydroxyapatite coating
Publication date: Available online 8 December 2018Source: Journal of Saudi Chemical SocietyAuthor(s): Chunlei Zhang, Zhiguo Xiao, Tongtong Qin, Zhengpeng YangAbstractUric acid (UA) produced from purine metabolism is rather harmful to human health when its concentration is high. To better understand the application of hydroxyapatite (HAP) as an adsorbent for UA removal, quartz crystal microbalance (QCM) technique was employed to in situ investigate the adsorption behavior of UA on nanosized HAP coatings. This work was mainly focused on the mechanism and kinetics of UA adsorption. The obtained results showed that nanosized H...
