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
A novel decyanogenative coupling of α-cyanoimines mediated by samarium. A facile route to α-diketimines

, p. 102 - 103 (2007/10/03)
Conversion of α-cyanoimines 1 into α-diketimines 2 has been achieved successfully by using samarium diiodide in dry tetrahydrofuran in high yields without formation of anilinoanil 3, 1,2-diamines 4 or anilides 5.
A novel reductive dimerization/oxidative dehydrogenation of aldimines mediated by lanthanoid metals

A lanthanoid metal-mediated novel reductive dimerization/oxidative dehydrogenation of a variety of aldimines has been achieved. Aromatic aldimines (1) were dimerized in the presence of 0.5 mol of ytterbium metal (Yb) and 1-naphthaldehyde (1-NpCHO) to give
