Предмет изобретени 1.Способ получени р-роданэтнловых эфиров тиоарсинистых кислот, отличающийс тем, что тиоцианаты арсинов подвергают взаимодействию с этиленсульфидом при температуре 20-50°С.This invention relates to the field of arsenic esters. A method of preparation was proposed (3-rhodoethyl esters of thioarcinic acids. The method consists in that arsine thiocyanates are exposed to ethylene sulfide. The process is carried out at a temperature of 20-50 ° C. It is expedient that the Westp reaction takes place in an organic solvent, for example benzene. The yield is 80-100 The esters obtained in this way can be used as fungicides and intermediates for the synthesis of physiologically active substances. EXAMPLE 1. (3-P one-ester ether d and meth and t and o arc and n and t o and acids. To 0.05 g dimeti cyanate Larsine, while stirring, is added dropwise 0.08 g of mol of ethylene sulfide, keeping the temperature no higher than 25 ° C. The reaction mass is not stirred at 25 ° C for 1 hour and left to stand at room temperature for 12 hours, then the excess ethylene sulfide is distilled off and the residue fractionated under vacuum, 10.2 g (92.3%) of the substance are obtained with a boiling point of 104–105 ° C (1 mm Hg), df 1.5298, n, 1.590. lt and oar and n-petite acid are prepared under the conditions of example 1 from 0.05 g-mol of diethylaarsin thiociaiate and 0.07 g-mol of ethylene sulfide.

To a solution of 0.05 g mol of phenoxarsine mol-thionianate in 50 ml of benzene, 0.1 g of ethnlenesulfide is added dropwise, maintaining the temperature in the range of 30-40 ° C. The reaction was stirred at the same temperature for 4-6 hours, an excess of ethylene sulfide and benzene was distilled off in vacuo, and 17.9 g (99%) of the product was obtained in the residue, mp. 114 ° C.
