The reaction of the lithium salts of 5-nitro-2-R-1,3-dioxanes with 2,4-dinitrochlorobenzene leads to the formation of 2-R-5-nitro-5-(2,4-dinitrophenyl)-1,3-dioxanes with the axial-equatorial arrangement of the nitro and 2,4-dinitrophenyl substituents.

Study of the reaction of the 5-nitro-1,3-dioxane lithium salt with derivatives of p-nitrobenzoic acid made it possible to propose optimum conditions for the synthesis of 5-aryl-5-nitro-1,3-dioxanes.The radical-ion nature of the reaction was demonstratyed

5-Nitro-5-(5-nitro-1,3-dioxa-5-cyclohexyl)-1,3-dioxane and 5-(1,3-dioxa-5-cyclohexylidene)-1,3-dioxane are formed and lithium bromide and nitrite are released in the reaction of 5-bromo-5-nitro-1,3-dioxane with the lithium salt of 5-nitro-1,3-dioxane in DMSO at 20 deg C.The selectivity of the formation of the reaction products depends on the ratio of the reagents. 5-Nitro-5-(2-nitro-1-methylethyl)-1,3-dioxane, 5-nitro-5-(5-nitro-1,3-dioxa-5-cyclohexyl)-1,3-dioxane, and 2,3-dimethyl-2,3-dinitrobutane are formed in the reaction of 5-bromo-5-nitro-1,3-dioxane with the lithium salt of 2-nitropropane.The reaction is accelerated by UV radiation and is retarded in the presence of the inhibitors of radical reactions.

The reaction of the lithium salts of 5-nitro-1,3-dioxanes with p-nitrobenzyl chloride in DMFA at 0 deg C leads to the formation of 5-nitro-5-(4-nitrobenzyl)-1,3-dioxanes.The reaction is stereospecific and has a radical-anion mechanism.In the case of the l
