UEBER DAS SYNTHESEPOTENTIAL TRIFLUORMETHYL-SUBSTITUIERTER ZINN-HETEROCYCLEN
Burger, Klaus,Geith, Klaus,Sewald, Norbert
, p. 105 - 122 (2007/10/02)
4,4-Bis(trifluoromethyl) substituted heterodienes of type (F3C)2C=N-C(R1)=X (X = O, S, NR2) react with tin(II) compounds to give cycloadducts.The cycloaddition process causes an 'Umpolung' at the carbon
Reaction Behaviour of Trifluoromethyl Groups. Synthesis of 1,3-Azoles from Trifluoromethyl-substituted Hetero-1,3-dienes
Burger, Klaus,Ottlinger, Ralph,Goth, Herbert,Firl, Joachim
, p. 2494 - 2507 (2007/10/02)
4,4-Bis(trifluoromethyl)-substituted 1-oxa-3-aza-1,3-butadienes 1, 1-thia-3-aza-1,3-butadienes 2 as well as 1,3-diaza-1,3-butadienes 3 on heating with tin(II) chloride yield 5-fluoro-4-trifluoromethyl-substituted oxazoles 4, thiazoles 5, and imidazoles 6,
SELEKTIVE EINFUEHRUNG VON FLUOR UND TRIFLUORMETHYLGRUPPEN IN HETEROCYCLISCHE SYSTEME SYNTHESE VON 5-FLUOR-4-TRIFLUORMETHYL-OXAZOLEN
Burger, Klaus,Goth, Herbert
, p. 585 - 590 (2007/10/02)
N--imidoylchlorides 4 on heating with trimethyl phosphate yield 5,5-difluoro-4-difluoromethylen-2-oxazolines 5.In the presence of caesium fluoride the latter rearrange to give 5-fluoro-4-trifluoromethyl-oxazoles
