The research is concerned with the synthesis of fourteen acidic and basic compounds, derived from N-formyl pipyridine (I) as a mother compound. They are in forms of syn and anti oxime and Schiff bases having different substituents. These compounds are prepared by reaction of (I) with a suitable primary amines as hydroxyl amine hydrochloride, o, m and p – phenylene diamine, 4 – nitro – o – phenylene diamine, o, m and p – toluidine and others.
The compounds under study are identified by using chemical and physical methods. The former method includes chemical solutions of FeCl3 and 2,4-dinitrophenyl hydrazine as selective reagents for qualitative analysis of oxime or phenol and carbonyl groups respectively. The last method includes measurements of melting or boiling points and the available UV and IR spectra of compounds.
