Bismuth Triflate as Novel and Efficient Catalyst for the Synthesis of β-Aminosulfides. — In the case of N-benzyl- and N-tosyl-2-aryl aziridines such as (I) the preferred
cleavage occurs at the benzylic position of the aziridine ring. In the case of N-tosyl-2-alkyl aziridines such as (IV) the cleavage is at the less hindered aziridine-ring carbon. Similar results are obtained with Sc(O-Tf)3 as the catalyst. — (YADAV*, J. S.;
