A 2-bromo -2, 3, 3, 3- four fluorine propionic acid method for synthesis of ethyl

The invention relates to a synthetic method of 2-bromine-2,3,3,3-tetrafluoropropionic acid ethyl ester. 2,3,3,3-tetrafluoropropionic acid is taken as an initial raw material, a brominating agent is used for substituting hydrogen on a carbon atom at a site 2, so that the 2-bromine-2,3,3,3-tetrafluoropropionic acid is obtained, and then reaction is carried out on concentrated sulfuric acid and ethyl alcohol, so that the 2-bromine-2,3,3,3-tetrafluoropropionic acid ethyl ester is obtained. The synthetic method of the 2-bromine-2,3,3,3-tetrafluoropropionic acid ethyl ester has the advantages that reaction conditions are simple and mild, the 2-bromine-2,3,3,3-tetrafluoropropionic acid ethyl ester target product can be obtained through reaction in two steps, and the total yield is 75%.

Reactions involving hexafluoropropylene oxide: Novel ring opening reactions and resolution of a racemic mixture of a bromofluoro ester, ultrasound mediated Reformatsky reactions and stereoselectivity

A novel ring opening reaction of hexafluoropropylene oxide (HFPO) 1 with lithium bromide/zinc bromide and subsequent reaction of the resulting acyl fluoride with primary and secondary alcohols gave bromofluoro esters 2, 3, 4 and 7. Reaction of the corresponding acyl fluoride with water leads to acid 9 which on treatment with dehydroabietylamine 10 gave the diastereomeric salt 11. Resolution of 11 and subsequent hydrolysis and esterification reactions led to enantiomerically pure ester 12. Reformatsky reactions with 2 were studied which gave the alcohols 6 and 5. A Reformatsky reaction of 12 with formaldehyde afforded an alcohol 13 which is indicated by NMR spectroscopy in the presence of a chemical shift reagent to have proceeded stereoselectively.
