Ogle, James W.,Miller, Stephen A.
scheme or table, p. 5728 - 5730 (2010/01/31)
The catalytic activity of iridium-mediated transfer hydrogenation is readily tuned by electronic variation of the ligated tetraaryl-N-heterocyclic carbene and the installation of electron donating groups on the N-aryl substituents is more important than o

(Chemical Equation Presented) A new method for synthesizing symmetrical N-heterocyclic imidazolium salts is described. Catalytic coupling of aldimines with cyanide followed by oxidation gives α-diketimines, which can then be cyclized with formaldehyde in
