TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (disclosed): 2-amino-3-Bis(3,5-dialkoxy phenylmethyl)amino-2(z)-butene-1,4-dinitrile of formula (1) and 3,5-dialkoxy benzaldehyde of formula (2) are reacted with trifluoroacetic acid in presence of alcohol and further in presence of sodium borohydride to obtain maleonitrile of formula (3). The maleonitrile (3) is reacted with methyl iodide in presence of sodium hydride and tetrahydrofuran/dimethylformamide to obtain dimethylated maleonitrile of formula (4). The compound (4) is heat-refluxed with mixture of formamide and potassium t-butoxide in presence of magnesium ethoxide, to obtain the tetraaza porphyrin derivative. SPECIFIC COMPOUNDS - 8 Tetraaza porphyrin derivative compounds are disclosed, e.g. (octakis(methyl-3,5-diundecyloxy phenylmethyl)amino tetraaza porphyrin) of formula (II), tetrakis(methyl-3,5-di-dodecyloxy phenylmethyl)amino tetraaza porphyrin, tetrakis(methyl-3,5-repository decyloxy phenylmethyl)amino tetraaza porphyrin, tetrakis(methyl-3,5-ditetra decyloxy phenylmethyl)amino tetraaza porphyrin and tetrakis(methyl-3,5-dipenta decyloxy phenylmethyl)amino tetraaza porphyrin.    EXAMPLE - 2.308 g 2-amino-3-(3,5-diundecyloxy phenylene)amino-2(z)-butene-1,4-dinitrile and 1.961 g 3,5-diundecyloxy benzaldehyde were stirred with trifluoroacetic acid in presence of 25 ml tetrahydrofuran and 10 ml methanol at room temperature in argon atmosphere. The reaction mixture was concentrated by removing solvent to obtain residue. The residue was stirred with 0.388 g of sodium borohydride in presence of 20 ml tetrahydrofuran and 20 ml ethanol at room temperature in argon atmosphere. The reaction mixture was distilled and extracted with dichloromethane-water, and the organic layer was washed with water, filtered and concentrated to obtain 2.673 g bis(methyl-3,5-diundecycloxy phenylmethyl) amino maleonitrile. 2.654 g of obtained maleonitrile was mixed with 0.184-0.307 g sodium hydride and 0.45 ml methyl iodide in presence of 20 ml tetrahydrofuran and 10 ml dimethylformamide and a small amount of methanol was added. The reaction mixture was extracted with dichloromethane-water and the organic layer was separated and concentrated to obtain 0.828 g of 2,3-bis(methyl-3,5-diundecyloxy phenylmethyl)amino maleonitrile. 1.886 g of obtained maleonitrile was heat-refluxed with 0.08 ml formamide and 0.216 g potassium-tert-butoxide in presence of 0.221 g magnesium ethoxide in 7 ml 1-proponal in argon atmosphere. The reaction mixture was cooled to room temperature and hydrolyzed using sodium hydrogen carbonate in an ice bath. The reaction mixture was extracted with dichloromethane-water, and the organic layer was washed with water, filtered, concentrated and purified using dichloromethane in silica gel column chromatography to obtain 0.159 g (octakis(methyl-3,5-diundecyloxy phenylmethyl)amino tetraaza porphyrin).
