Review on Azomethine-Compounds with Their Applications
Abstract: Azomethine derivatives are very important and the initiating compound for most synthetic chemistrycompounds in all their fields. Since R, R1 is an alkyl or aryl group, the first to prepare and isolate itwas the German scientist Hugo Schiff in 1864 from the condensation of the carbonyl group (aldehyde,ketone) with a primary amine compound (aliphatic, aromatic). During the past few decades there hasbeen great interest in Schiff base compounds. The rules …
