Tetraselenotungstate 1 reacts with simple (N-tosylaziridinyl)-methyl tosylate derivatives to give allylamine derivatives as the only products by an unprecedented selena-aza-Paynetype rearrangement. When the methodology is extended to disubstituted (N-tosylaziridinyl)methyl tosylates, regio- and stereospecific ring-opening of the aziridines occurs to afford allylamine derivatives as the major products
Aziridinemethanol sulfonate esters react with tetrathiomolybdate 1 to give thiirane derivatives as the major product and cyclic disulfides as minor product under mild reaction conditions via an unprecedented thia-aza-Payne-type rearrangement. Interestingly, when the reaction of 1 was carried out with 2-aziridino-cyclohexanol derivatives it resulted in the formation of thia-bicyclo[3.1.1]heptane or

Sharpless epoxidation, aminohydroxylation, and aziridination procedures provide substrates for the tellurium-triggered synthesis of racemic and non-racemic allylic amines under phase-transfer conditions.
