Preparation and spectroscopic identification of some sulphamerazine imines

Abstract EN

Sulphamerazine Imines derived from Sulphamerazine and selected aromatic aldehydes, namely, 2- Hydroxy-1-naphthaldehyde, 4-Hydroxy benzaldehyde, salicaldehyde, 3-Ethoxy Salicaldehyde and p- Toluealdehyde have been synthesized and characterized by IR, 1HNMR and GC.

Mass spectroscopy .The results revealed that , all compounds exit in imino form where the chemical shift (σ )of the imino proton (HC = N ) are within the range 8.5- 9.6 .

The strong intrahydrogen bonding was observed in compounds containing OH group in ortho position of aldehydes ( compounds 1, 3 and 4) as indicated by the downfiled OH proton signals which appeared within the range 12-15.5 ppm .
