Abstract
The structure and the isomerism of homologous series such as 4-(ω-hydroxy)alkyloxy-4'-cyanazoxybenzene, 4-(ω-hydroxy)alkyloxy-4'-cyanazobenzene, 4-oktyloxy-4'-cyanazoxy-benzene, 4-(ω-hydroxy)hexyloxy-4'-formylazobenzene were studied by one-dimensional and two- dimensional NMR spectroscopy. The isomer azoxybenzene structure was established by two-dimensional correlation NMR spectroscopy methods, in particular, 1Н, 15N-HMBC experiment.

Keywords: azobenzenes, azoxybenzenes, position isomers, cyano group, formyl group, one-dimensional and two-dimensional NMR spectroscopy
