, p. 472 - 475 (2005)
The reactions of hexafluoroacetone and methyl trifluoropyruvate acyl- and ethoxycarbonylimines with benzamidines afford fluoro containing heterocycles of four structural types: dihydrotriazines, dihydrotriazinones, imidazoles, and imidazooxazoles.

Kapran, N. A.,Yagupol'skii, Yu. L.,Cherkasov, V. M.
, p. 1063 - 1066 (2007/10/02)
The reaction of bis(trifluoromethyl)ketimine with the amidines of benzoic, trichloroacetic, and trifluoroacetic acids yields the products of the addition of the acid amidines to the C=N bond of the ketimine which are converted upon heating through intermediate 1,3-aza-1,3-dienes to 1,2-dihydro-2,2-bis(trifluoromethyl)-4,6-substituted 1,3,5-triazines.

2,2,6,6-Tetrakis(trifluoromethyl)-5,6-dihydro-2H-1,3,5-oxadiazines 3 on thermolysis undergo a retro Diels Alder reaction.On elimination of hexafluoroacetone 2 4,4-bis(trifluoromethyl)-1,3-diazabuta-1,3-dienes are formed, which are transformed into 4,4-bis
