REACTIONS OF POLYFLUOROCARBONYL COMPOUNDS AND THEIR TRIFLUOROACETYLIMINES WITH FUSED HETEROCYCLES

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.
