%X In contrast to the conventional strategy
of modifying the reactivities
and selectivities of the transition metal and organocatalysts by varying
the steric and electronic properties of organic substituent groups,
we hereby demonstrate a novel approach that the sigma (σ) nucleophilicity
of the imine arm can be significantly enhanced in a pseudodearomatized
PN3P* pincer ligand platform to reach unprecedented N-heterocyclic
carbene-like reactivity. Accordingly, the imine arm of the PN3P*Ni–H pincer complex efficiently catalyzes the hydrosilylation
of aldehydes, cycloaddition of carbon dioxide (CO2) to
epoxides, and serves as a ligand in the Ru-catalyzed dehydrogenative
acylation of amines with alcohols.
