Abstract
Azomethines are nitrogen-based 1,3- dipoles, consisting of an iminium ion next to a carbanion. They are used as ligands which are able to coordinate metal through imine nitrogen and another group, usually linked to carbonyl group. In fact, azomethine ligands are able to coordinate many different metals and to stabilize them in various oxidation states. They have been widely studied because of their application in many fields of fundamental and applied research. A number of azomethine used for the qualitative analysis, quantitive analysis [Kalaskar et. al, 2013]. Azomethine imines are used as intermediate in synthetic organic chemistry [Schantl et. al, 2004].
[Ashley et. al, 2013] have been synthesized azomethine imines using an intramolecular alkyene hydrohydrazation approach. They have been noted the increased reactivity associated with the use of 3,5 – bis (trifluoromethyl) benzhydrazides [Loiseau et. al, 2011]. They also speculated that the bis (trifluoromethyl) benzoyl group would stabilize the negative charge of the dipole sufficiently to allow isolation of azomethine imines from appropriate precursors as shown in Table (1).
