TBS-protected or NH-sulfonimidamides react with β-alkoxyvinyl trifluoromethylketones under solvent-free mechanochemical conditions to give 3-trifluoromethyl-substituted three-dimensional 1,2,6-thiadiazine 1-oxides. C4-Functionalized products can be obtained by starting from cyclic enones and brominations of the initially formed heterocycles. The stability of the products was investigated by varying the pH value
