N double bonddehydrogenative couplingimidationiridium complexesThe efficient construction of CN double bonds has been achieved by the Ir-catalyzed intramolecular acceptorless dehydrogenative cross-coupling of tertiary amines and amides. An iridium/2-hydroxypyridine complex was identified as the highly efficient...

The IR results confirm that lanthanum tri-caprylate has an ionic character and the fatty acid exists as a dimer. The X-ray analysis supports the view that the metal soap has a double layer structure with molecular axes slightly inclined towards the basal plane. The kinetics of thermal ...

The double bond character of the C(4) C(5) interaction [1.309(7)] suggests the enammine nature of the N(H)C(Me)C(CN) fragment which originates from condensation of two acetonitrile molecules. A mechanism for the formation of 2a– c is proposed in light of the 13C-NMR and IR ...
