Av. Fokin et al., REACTIONS OF POLYFLUOROCARBONYL COMPOUNDS AND THEIR TRIFLUOROACETYLIMINES WITH FUSED HETEROCYCLES, Russian chemical bulletin, 45(5), 1996, pp. 1178-1181
C-Hydroxy- and C-aminoalkylation of iminodibenzyl, iminostilbene, phen
oxazine, and phenothiazine with hexafluoroacetone, methyl trifluoropyr
uvate, and their trifluoroacetylimines were investigated, The substitu
tion occurred at one or several para- and ortho-positions to the N ato
m of the heterocycles. In the case of methyl trifluoropyruvate and its
derivative the substitution in the ortho-position was accompanied by
the formation of lactams.
