Abstract
The addition of selenium tetrabromide to the olefinic bond of N-substituted allylacetic acid amides (reagent molar ratio 2∶1) proceeds counter to Markownikoff's rule with the formation of tetrahydrofuran derivatives. The addition of tellurium tetrahalides under the same conditions (reagent molar ratio 1∶1) proceeds in accordance with Markownikoff's rule with the formation of tetrahydropyran derivatives.
