A proline-squaraine ligand (Pro-SqEB) that demonstrates high levels
of stereoselectivity in olefin cyclopropanations when anchored to
a Rh2II scaffold is introduced. High yields
and enantioselectivities were achieved in the cyclopropanation of
alkenes with diazo compounds in the presence of Rh2(Pro-SqEB)4. Notably, the unique electronic and steric design of this
catalyst enabled the use of polar solvents that are otherwise incompatible
with most RhII complexes.
