2-Bromo-2-perfluoroalkyl acids are converted into the corresponding esters by a reaction of alcoholysis in the 2-chloroethanol. The action of zinc on perfluoroalkylated bromo-esters resulted in the bromine reduction products formation via zinc organi

Direct substitution and elimination reactions of the fluorine atoms of difluoromethylene CF2α groups of nonspaced perfluoroalkyl chains, CF3 groups are very difficult to achieve. But, they become feasible with fluoro-alkenes, alkynes, imines or carb

A rapid one-pot reaction of epoxides with ethyl mercaptoacetate furnishing 1,4-oxathian-2-ones in the presence of a catalytic amount of eco-friendly triton B is reported. High regioselectivity is due to the nucleophilic attack on the less sterically

An efficient oxirane ring opening of polyoxyethylene diglycidyl ethers with sodium amide has been achieved for the first time under catalyst-free conditions. This reaction is highly regioselective and affords the corresponding bis (β-aminoalcohols)

The synthesis of new 6-perfluoroalkylated 1,2,3-triazolo-1,4-oxazine ethers and thioethers as fused exo -heterobicyclic compounds was achieved from terminal perfluoroalkyl oxiranes by azide ion ring opening and propargylation reactions followed by a

Classic direct synthetic methods failed to transform bis(perfluororalkylallyl) dioxyethylene ether into the corresponding bis(perfluoroalkyl oxirane). This transformation was instead realized using a mixture of mercuric acetate/bromine to produce the

Free radical addition of perfluoroalkyl iodides to bis(propargyl) polyoxyethylene ethers 1 , using AIBN as initiator, affords the corresponding EE/EZ and ZZ bis(perfluoroalkylallyliodo) ethers 2 . Dehydroiodation of compounds 2 produces bis(perfluoro
