Fluoroalkyl derivatives of protected glycerol by nucleophilic substitution. Fluorine-containing amphiphilic mono- and bis-methacrylates
摘要:
The tosylate of protected glycerol (solketal, 4-(hydroxymethyl)-2,2-dimethyl-1,3-dioxolane) was fluoroalkylated by a nucleophilic substitution reaction with sodium polyfluoroalkoxides. On deprotection, 3-O-fluoroalkylated glycerol was obtained which was converted to mono-and bis-methacrylates; analogous methacrylate derivatives were prepared from 3,3,4,5,5,5-hexafluoro-pentane-1,2-diol.

Synthetic opportunities and mechanism of catalysis of the reaction of polyfluororalkylchlorosulfites with saturated monohydric alcohols are considered. Kinetic measurements and quantum-chemical calculations showed that polyfluoroalkylation of these compounds proceeded through the step of complex formation involving reagents and catalyst followed by liberation of hydrogen chloride and sulfur dioxide and formation of polyfluoroalkyl ethers.
