Abstract
Two 3-diethylaminomethyl-5-R-salicylic aldehydes were obtained and studied in chloroform solutions by FTIR and NMR spectroscopy. The existence of an e quilibrium between the structures with OH ...=O=C and N ... HO intramolecul ar hydrogen bonds was suggested. In the ease of compound 1 (R = OCH3) the O H ... O=C intramolecular hydrogen bond was more favorable whereas in the ca se of compound 2 (R = Br) the structure with the OH ... N intramolecular hy drogen bond was predominant.
