Popis:	Reaction of two-fold excess of diethyl 3-methyl-1,2-butadienylphosphonate with 1,10-diaza-18-crown-6 leads to the formation of an adduct whose molecule includes two 1-phosphoryl-3-methyl-2-butene fragments bound together by a crown bridge with the anti location of organophosphorus groups relative to the macrocycle plane. The 1,2-multiple bond of the phosphonate is involved in the reaction. Extraction properties of the diphosphorylated crown ether toward alkali metal picrates were studied.
