Determination of Hydroxyl Groups and Alkoxysilanes: Acid-catalyzed Acetylation Methods - Organic Functional Group Analysis: Theory and Development - CHAPTER 4ELSEVIEROrganic Functional Group Analysis Theory & Development
Carboxylic acidmolecules have an -OH next to a carbonyl group. This functional group is found at either the beginning or end of a molecule. Functional Groups in Organic Synthesis Lesson Summary Register to view this lesson Are you a student or a teacher?
Reason: alkene has high electron density due to its C=C bond, which attracts electrophiles to attack the double bond. Acid-base property: neutral Combustion Electrophilic addition Reagent: H2O(g)Catalyst: concentrated H3PO4 (phosphorus acid)Condition: 330℃ & 6MPaEquation: CH2=CH2+H2O→CH3CH2OH...
(Chalmers and Watts, 1972b), and even among the lower-molecular-weight acids, intermolecular hydrogen-bonding reduces volatility. As a result it is necessary to convert the carboxylic acid group into a non-polar volatile thermally stable derivative, such as an ester, prior to gas chromatography....
photocatalysis14and sensing15. The addition of functional groups to the p-benzenedicarboxylic acid (BDC) linkers creates a large class of UiO-66-X materials with various properties16,17. For instance, amino modified UiO-66-NH2is widely used in the synthesis of single atom catalyst (SACs), due...

Now, using a serine-derived chiral carboxylic acid, an electrocatalytic decarboxylative transformation enables efficient and stereoselective access to diverse amino alcohols. This method is scalable, modular and could offer rapid synthesis of medicinal compounds and key building blocks. Jiawei Sun , ...
