Abstract

1. Способ получения 5-метоксикарбонил-1,3-дитиана общей формулы (1), обладающего фунгицидной активностью,отличающийся тем, что насыщенный сероводородом водный раствор формальдегида (37%) подвергают взаимодействию с диметиловым эфиром малоновой кислоты в присутствии катализатора CoClпри мольном соотношении формальдегид: сероводород: диметиловый эфир малоновой кислоты: CoCl, равном 3:2:1: (0,03-0,07), при комнатной температуре (~20°С) и атмосферном давлении в течение 4-6 ч.2. Применение 5-метоксикарбонил-1,3-дитиана в качестве фунгицида по отношению к Bipolaris sorokiniana.1. A method of obtaining 5-methoxycarbonyl-1,3-dithian of the general formula (1) having fungicidal activity, characterized in that the aqueous solution of formaldehyde saturated with hydrogen sulfide (37%) is reacted with malonic acid dimethyl ether in the presence of a CoCl catalyst in a molar ratio of formaldehyde : hydrogen sulfide: malonic acid dimethyl ether: CoCl, equal to 3: 2: 1: (0.03-0.07), at room temperature (~ 20 ° C) and atmospheric pressure for 4-6 hours. 2. The use of 5-methoxycarbonyl-1,3-dithian as a fungicide with respect to Bipolaris sorokiniana.
