A novel route for the synthesis of piperazine from N-(2,3-dihydroxypropyl)ethylenediamine over composite photocatalysts.
Semiconductor loaded zeolite composite catalysts (5 wt% TiO2/Hbeta) have been used to photocatalytically synthesize piperazine from N-(2,3-dihydroxypropyl)ethylenediamine with yields up to 59.0 mol%.
