Cooperative catalysis of a cationic Ru complex, DBU, and NaPF6 enabled
activation of acetonitrile as a nucleophile under mild basic conditions. The
nucleophilic 1,2-addition of in situ-generated, Ru-bound, metalated nitrile to
aldehydes and imines proceeded smoothly.

In the presence of SiCl4 and a catalytic amount of a chiral
phosphoramide, silyl ketene imines undergo extremely rapid and high yielding
addition to a wide variety of aromatic aldehydes with excellent diastereo- and
enantioselectivity. The nitrile function serves as a useful precursor for
further synthetic manipulation.
