A. Honda et al., RHODIUM(I)-MEDIATED OR IRIDIUM(I)-MEDIATED EQUILIBRATED REACTIONS OF ACTIVATED 2,3-CIS-ALKYL-2-VINYLAZIRIDINE AND TRANS-3-ALKYL-2-VINYLAZIRIDINE, Synlett, (9), 1998, pp. 969
Rhodium(I)- or iridium(I)-complexes-mediated equilibrated reactions of
both 2,3-cis and 2,3-trans-N-arylsulfonyi-3-alkyl-2-vinylaziridines a
fforded 2,3-cis- and trans-stereoisomeric mixtures in favor of 2,3-cis
-isomers. Addition of a trialkyl phosphite such as trimethyl phosphite
is critical to the equilibrated reactions. Important factors for the
reactions are discussed.
