Reaction of nitroalkanes with polyfluoroaromatic compounds

, p. 33 - 37 (2013/01/15)
Nitromethane and nitroethane in the presence of DBU attack preferentially the para position of pentafluorobenzonitrile and methyl pentafluorobenzoate to give the addition products in good yield. The resulting nitro compounds can be converted to tetrafluorotoluene or ethyl benzene derivatives by tri-n-butyltin hydride. TiCl3 solution neatly transforms the nitroethyl compounds into corresponding ketones. With a base, the nitro compounds can be used to extend chain length using Michael acceptors like ethyl acrylate and acrylonitrile.

The syntheses and crystal structures of a series of fluoro-substituted halogeno (Cl, Br, I)-cyano-stilbenes containing donor and acceptor groups (D-π-A) are reported. These molecules show a tendency to form antiparallel chain-like structures and herringbone packing, crystallising predominantly in a centric space group. However, second harmonic generation measurements bear evidence for orientational disorder leading to partial polar order below the ordinary X-ray structure determination limit. Some co-crystals are isostructural with their components. The non-fluoro as well as the halogeno-fluoro substituted components of co-crystals seem to impose their crystal structure on the complementary fluoro- or cyano-fluoro substituted components. Co-crystallization enhanced the deviation from centrosymmetry.

THE MONO-ALKYLDECYANATION OF TETRAFLUOROTEREPHTHALONITRILE BY REACTION WITH GRIGNARD REAGENTS
Milner, David J.
, p. 147 - 152 (2007/10/02)
Treatment of tetrafluoroterephthalonitrile in THF with alkyl Grignard reagents gives the corresponding 4-alkyltetrafluorobenzonitrile in about 60percent yield.The scope and limitations of this transformation are reported.
Halogenated esters

, (2008/06/13)
Compounds of formula I wherein R1 and R2 are each selected from halomethyl and halo and R is nitro, cyano, lower alkoxycarbonyl, lower alkylcarbonyl, or di- or trifluoromethyl, and n has a value of zero to four, and compositions comprising them are useful as insecticides in agriculture, horticulture and other outlets. They may optionally be combined with other pesticides and/or synergists. The compounds may be prepared by conventional esterification processes from the corresponding acids and appropriately substituted benzyl alcohols or halides, some of which are novel. STR1
