Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 72824-04-5, formula is C9H17BO2, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Safety of 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
Li, Mengwen;Ao, Shen;Liang, Yueqi;Hao, Zhen;Hao, Xiaohui;Liu, Xueliang;Sun, Xinchao;Yang, Yunxu research published 《 The selective and sensitive detection of formaldehyde by ZIF-90-LWvia aza-Cope rearrangement》, the research content is summarized as follows. Formaldehyde (FA), as one of the simplest reactive carbonyl species (RCS), is widely known as an environmental toxin and carcinogen. In this work, a new ZIF-90 type material (ZIF-90-LW) was synthesized and investigated, which combines the two strategies of “2-aza-Cope rearrangement” and “MOF structure”, by the combination of a pre-functionalized 2-allylaminoimidazole ligand and Zn2+ salt under solvothermal conditions. From this, the hurdle of selectivity over other carbonyl compounds (RCS) could be overcome despite their similar electrophilic reactivities to FA, and a prominent fluorescence turn-on type signal was realized through the 2-aza-Cope rearrangement mechanism. A good linear relationship (R2 = 0.9979) was obtained by fitting the fluorescence intensity towards FA from 0 to 25 mM, and the detection limit of ZIF-90-LW for FA was 2.3 μM. In addition, it also showed potentially useful sensing ability for the detection of FA in the gas phase, and might therefore be used to rapidly detect FA with a response time of 28 s in the liquid phase. All of the above features clearly demonstrate that ZIF-90-LW has great potential for sensitive and selective recognition of FA in the environment.
72824-04-5, Allylboronic acid pinacol ester is a useful research compound. Its molecular formula is C9H17BO2 and its molecular weight is 168.04 g/mol. The purity is usually 95%.
Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., Safety of 2-Allyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
