    The purpose of the invention is to search for new compounds with valuable properties.
    Example 1. To a mixture of 86 g (1.3 mol) of crushed potassium hydroxide (85%), 100 g (1, A5 mol) of 1,2,4-triazole in 1000 ml of dimethyl sulfoxide was added over 8 hours at simultaneously stirring f. and when heated (145 C) in a nitrogen atmosphere solution. 363 g (1.025 mol) cis / trans-2-bromomethyl-2- (2,4-dichlorophenyl) -5-methyl-4-methyl-1,3-dioxolane
    in 250 ml of dimethyl sulfoxide. After stopping the addition of the solution, the resulting dark brown mixture was stirred and heated for another
    6h After cooling, doZ l of 1,1-hydroxy-bis-ethane was added to suy and up to 6 l of water, agitated and the resulting layers were separated from each other. The organic layer was washed to a neutral state, dried, filtered and evaporated, with the result that a highly viscous brown oil formed, which was distilled off in vacuo, resulting in 271 g of obtained
    (77.3%) of a highly viscous yellow oil having a boiling point of I36-. (at a pressure of 0.003 mm Hg) which crystallized at delay. After three successive processes of recrystallization of this oil from a mixture of 2,2-hydroxy-bis-propane with hexane, 2- (2,4-dichlorophenyl-4-ethyl-5-methyl-1,3-dioxolan-2-ylmethyl | -Sh -1, 2,4-triazole in the form of white crystals with m.p., 109-113 C. The following compounds were obtained in a similar way (Table 1).,.,.
    Example 2. A solution of 27 g

    back reflux for 8h using a water trap. After cooling, the solution was washed with an aqueous solution of sodium hydrogencarbonate, evaporated. An excess of 2,4-dichlorfenachenbromide was removed in vacuo (at
    0.01 mm Hg) in an oil bath at 150 ° C, resulting in 30 g of 2- (bromomethyl) -2- (2,4-dichlorophenyl) - hexahydrobenzodioxole being obtained as a viscous melle containing mainly the cis isomer. 3g (0.082 mol) of 2- (bromomethyl) -2- (2,4-dichlorophenyl) -hexahydro.benzodioxole was added to peremetannoe and heated (130 ° C) mixture of 1 1 1 g (0.1 mol (0.1 mol) I, 2.4 triazole in dimethylformamide. After stopping the addition, the reaction mixture was stirred for another 20 hours at a temperature in the range of 130-140 ° C. The dimethylformamide was evaporated in vacuum, the residue was evaporated in water and extracted with mixture 1 , 1-oxy-bis-ethane with ethyl acetate. The organic layer was separated, dried and evaporated, with the result that 25 g of a viscous gum, which was purified by chromatographic separation in an adsorption column filled with silica gel using dichloromethane as eluent. The pure fractions were collected and the eluent was evaporated, after which 12 g of a yellow gum were obtained. that this resin is 2- (2,4-dichlorophenyl) hexahydrobenzodioxol-2-ylmethyl -1H-1, 2,4-triazole. Example 3. A. Carrying out the process in the same manner as described in example 2 in part 1, and using trans-1,2-cyclohexanediol instead of the technical 1,2-cyclohexanediol (cis + trans isomers), trans-2- (2 , 4-dichloro phenyl) hexahydrobenzodioxol-2-ylmethyl - 1H-1, 2,4-three a sol in the form of a viscous oil. B. 5 g of 1,2,4-triazole (0.072 mol and 4 g of pure potassium hydroxide were heated to reflux in absolute ethanol for 1 hour. Ethanol was evaporated in vacuo and the potassium salt 1 thus formed, 2,4-triazole was absorbed in 200 ml of dimethyl sulfoxide. To this solution was added 18.5 g (0.05 mol) of trans-2- (2,4-dichlorophenyl) hexanhydrobenzodioxol-2-yl-methyl-1H-1,2 , 4-triazoles, and the entire reaction mixture was stirred for 8 hours at 140 ° C. The reaction mixture was cooled and diluted with one liter of water. The aqueous solution was extracted several times with 1.1- k-And-bis-ethane, the organic layers were separated and the combined extracts were niHBiuiH. 4 ml of nitric acid (65%) were added to them with simultaneous stirring, resulting in white crystals. The crystals were filtered to obtain 15 g of nitrate trans- 2- (2,4-dichlorophenyl) hexahydrobenzodioxol-2-ylmethyl -1H-1, 2,4-trg.azole with mp 153-155 C. The following cis-ketals were obtained in a similar way (Table 2) . The following trans-ketals were prepared in a similar manner (Table 3). In a similar manner, the following mixture was prepared: trans-ketals / gab.4. Example 4. In a stirred mixture, 9.1 parts of nitrate (2,4-dichlorophenyl) -2, -2-dimethoxyethyl - 1 H-imidazole and 120 part methane (mio) sulfonic acid was added 9 part 2.3-hexanediol and transfer was carried out for 1 hour at 40 ° C (exothermic reaction: the temperature rises to 80 ° C). The reaction mixture was added dropwise to a solution of sodium hydroxide and the resulting product was extracted with dichloromethane. The extract was washed with water, dried, filtered and evaporated. The residue was purified on a column of chromatography on silica gel using a mixture of trichloromethane and methanol (98: 2) as eluent. Pure fractions were collected, and the eluent was evaporated. The residue was salified with 4-methyl-2-pentanone ethandioate. The salt was separated by filtration and dried, whereby 0.8 parts (7.1%) of ethanedioate (2,4-dichlorophenyl) -4-methyl-5-proyl-1,3-dioxolan-2-ylmethyl - were obtained. 1H-imidazole (1: 1).
