Reaction of tetrafluoroethene oligomers. Part 17. Some reactions of (E/Z)-perfluoro-2,3-dimethylpenta-1,3-diene

(E/Z)-Perfluoro-2,3-dimethylpenta-1,3-diene has been reacted with cold meth anol to afford a monosubstituted product, whereas reaction in methanol cont aining triethylamine, even at ice temperature, formed a single multi-substi tuted product containing seven methoxy groups; these products have been ful ly characterised and their formation rationalised. Reactions of the diene w ith aniline and substituted anilines formed either pyrroloquinolines, azeti nes or oxoazetines. A rationalisation of the different reaction pathways in terms of the substitution pattern and electron demand of the subsituents i n the anilines is presented.
