The reactions of 1-aryl-2,2,2-trifluoroethanone oximes with tetrasulfurtetranitride (S4N4) in toluene at reflux gave 5-aryl-5-trifluoromethyl-4H-1,3,2,4,6-dithiatriazines 2, 1-aryl-2,2,2-trifluoroethanonyliden-aminosulfenamides 3 and sulfur in 0–37%, 7–53%, and 2–41% yields, respectively. Treatment of 2 with tributyltin hydride in the presence of azobisisobutyronitrile in benzene at 80° afforded 3
1-芳基-2,2,2-三氟乙酮肟与四氮化四硫(S 4 N 4)在甲苯中的反应在回流下产生5-芳基-5-三氟甲基-4 H -1,3,2,4,6- dithiatriazines 2,1-芳基2,2,2- trifluoroethanonyliden-aminosulfenamides 3和0-37%,7-53%的硫,和2-41%的收率,分别。在苯并偶氮二异丁腈存在下于80°下用氢化三丁基锡处理2,得到的3收率极高。

Certain phenyl amines have been prepared wherein the "methyl" carbon is substituted with a polyfluoroalkyl radical. The compounds form acid addition salts, exist in resolvable stereoisomeric forms, and are useful for treating hypertension. Formulations for human and veterinary medicine are described, as well as methods of use.
