FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing α-[(pentane-2,4-dion-3-yl) methoxy]-ω-[(pentane-2,4-dion-3-yl)methylsulphanyl]alkanes of formula (1)
Method involves reaction of formaldehyde with α,ω-mercaptoalkanol of general formula HO-(CH2)n-SH (where n = 2-4) for 30 minutes with subsequent addition of acetylacetone and catalyst NiCl2•6H2O in molar ratio CH2O:α,ω-mercaptoalkanol:acetylacetone:NiCl2•6H2O = 2:1:2:(0.03-0.07) in a mixture of solvents CHCl3:C2H5OH (1:1, vol) at room temperature (~20 °C) and atmospheric pressure for 6-8 hours.
EFFECT: obtained compounds can be used as selective complexons of metals for supramolecular systems and biologically active substances.
