General Description

1H,1H,2H,3H,3H-Perfluoroundecan-1,2-diol is a synthetic chemical compound belonging to the class of perfluoroalkyl substances (PFAS). It is a fluorinated alcohol with a molecular formula of C11H15F13O2 and a molecular weight of 508.2 g/mol. 1H,1H,2H,3H,3H-PERFLUOROUNDECAN-1,2-DIOL is commonly used in industrial applications as a surfactant, surface treatment agent, and in the production of fluoropolymer materials. It is known for its water and oil repellent properties, as well as its stability and resistance to heat, chemicals, and environmental degradation. However, concerns have been raised about the potential toxicity and environmental persistence of 1H,1H,2H,3H,3H-Perfluoroundecan-1,2-diol, leading to regulatory scrutiny and efforts to phase out its use.

Synthesis of F-alkyl α-hydroxy acids and esters from F-alkyl epoxides and F-alkyl α-bromo acids and esters from F-alkyl bromohydrins

F-alkyl α-hydroxy acids and F-alkyl α-bromo acids were prepared respectively by the nitric acid ring-opening oxidative reaction of F-alkyl oxiranes, and oxidation by chromic acid of F-alkyl bromohydrins. The synthesized acids were converted to the corresponding methyl esters which may prove to be useful in the synthesis of F-alkylated heterocycles.
