Lv. Saloutina et al., SYNTHESIS OF POLYFLUOROALKYLATED 1,4-DIAZINOLS AND 1,4-OXAZINOLS USING POLYFLUORO-2,3-EPOXYALKANES32+13, Journal of fluorine chemistry, 87(1), 1998, pp. 49-55
It has been found that the reactions of polyfluoro-2,3-epoxyalkanes wi
th ethylenediamine and 2-aminoethanol yield 2,3-di(polyfluoroalkyl)- 1
,5,6-trihydro-1,4-diazin-2-ols and -di(polyfluoroalkyl)-5,6-dihydro-1,
4-oxazin-2-ols, respectively. In the case of unsymmetrical oxiranes mi
xtures of regioisomeric heterocyclic compounds have been obtained. The
se reactions were found to give some by products-N,N'-bis(polyfluoroac
yl) ethylenediamines and N-polyfluoroacyl-2-aminoethanols. (C) 1998 El
