Preparation and Spectroscopic Identification of Some Sulphamerazine Imines


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 .
