Perfluorinated nitrogen-containing heterocycles

Perfluorochemicals make up an important area of fluorine chemistry, in particular with respect to industrial applications. " Among these, perfluorinated nitrogen-containing heterocyclic compounds have received attention for a variety of applications, and this topic will be discussed briefly in this section. 

Reactive perfluorinated nitrogen-containing heterocycles act as efficient traps for the butenyl anion generated from hexafluotobutyne and metal halides transproducts predominate. Perfluoropyridine also yields the oligomeric diene (197) (see...

Bicyehe nitrogen-containing heterocyclic compounds were also fluorinated by ECF. ECF of AT-methyl-decahydroquinoline forms a mixture of cis- and tra/j5-isomerie perfluorinated derivatives. Ring contraction and formation of per-fluorocyclohexanes are side processes. Trows-quinolizidine gives perfluoro-tra/w-quinolizidine (yield 16-23%) and a large amount of other compounds with unknown... 

Preparation of Perfluorinated Nitrogen and Nitrogen-Oxygen Containing Heterocycles A wide range of perfluorinated amines was prepared in last 60 years. Electrochemical fluorination is the main method used for the preparation of variety saturated perfluorinated heterocycles. Despite the low yields of perfluorinated materials, the process is reliable and can be used for the preparation of perfluorinated materials. Detailed reports on the use of ECF for the preparation of fluorinated materials can be found in several reviews published in last 40 years Major types of perfluorinated N-... 

This chapter is one of the first attempts of systematic review of the synthetic methods and chemistry of nonaromatic saturated and unsaturated perfluorinated heterocycles. It summarizes data on the synthesis and chemical transformation of perfluorinated six- and to some extent five- membered nonaromatic heterocyclic compounds containing oxygen, nitrogen, sulfur, selenium, and phosphorous. It should be pointed out that the review is not all-inclusive one, but it is an attempt to provide representative examples of synthetic methods and chemistry of perfluorinated nonaromatic hetero-cychc materials.
