Catalytic synthesis of aziridine from 1,2-diaminoethane

Abstract

The contact conversion of 1,2-diaminoethane over a tungsten trioxide catalyst at 240–580°C has been studied by an impulse chromatographic method. The basic reaction path under these conditions is unimolecular deaminocyclization to give aziridine (31–35%). Piperazine and triethylenediamine, products of bi- and trimolecular deaminocyclization, are present as products. The deamination process is accompanied by coupled dehydrogenation and hydrogenolysis reactions. Addition of the acid anhydrides SiO₂, P₂O₅ and B₂O₃ to the catalyst increases its activity but has only a negligible affect on the activation energy of the process.
