The reactions of 1-aryl-2,2,2-trifluoroethanone oximes with tetrasulfur tetranitride (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。
