Regioselective Cycloaddition of 1,2-Disubstituted Aziridines to Heterocumulenes Catalyzed by Organoantimony Halides

Nomura, Ryoki,Nakano, Takahiro,Nishio, Yoshitaka,Ogawa, Sachiko,Ninagawa, Akira,Matsuda, Haruo

, p. 2407 - 2410 (2007/10/02)

In the presence of catalytic amounts of organoantimony(V) halides such as Ph4SbI, Ph4SbBr, Ph3SbBr2, and Ph3SbCl2, the cycloaddition of aziridines 1a-g with heterocumulenes (phenyl isothiocyanate, carbon disulfide, and carbon dioxide) selectively gave ring-expanded cycloadducts 3a-d, f, g and 6e by α-cleavage of the aziridine rings. - Key Words: Organoantimony halides / Aziridines, cycloaddition of, α-cleavage of / Heterocumulenes
