[270]. In fact, the stepwise nature of [Ru 2 (hp) 4 Cl] catalyzed reaction accounts for
preferential allylic C–H bond functionalization over alkene aziridination which is
the favored product when dirhodium catalysts are used. The presence of a discrete
diradical intermediate further assists the selectivity for allylic C–H amination using
a diruthenium catalyst.
12 Concluding Remarks
Rh 2 (OAc) 4 and its derivatives are well recognized as catalysts for a wide array of
organic transformations. The catalytic reactions usually occur at axial site. The
isoelectronic [Ru
I –Ru
I ] are relatively less explored. Recent studies have revealed
that a multitude of reactions could be executed at sites trans to the [Ru–Ru] single
