Bismuth(III) Trifluoromethanesulfonate and Trifluoroacetate as Convenient and
Efficient Catalysts for Regio- and Chemoselective Ring Opening of Epoxides in
Reactions with Anilines. — The ring opening of epoxides (I) or (IV) by substituted
anilines in the presence of bismuth(III) trifluoromethanesulfonate is studied. Depending on the substituent on the oxirane ring secondary or primary alcohols of type (III) or
(V) are formed. Somewhat lower yields are obtained if bismuth(III) trifluoroacetate is
employed as catalyst. — (KHOSROPOUR, A. R.; KHODAEI, M. M.; GHOZATI, K.;
