Abstract
3,4 - Dichloro - tetrahydro thiophene - 1,1-dioxide is prepared by passing chlorine into a carbon tetrachloride solution of 2,5-dihydro thiophene-1,1-dioxide. The latter is prepared by heating a mixture of liquid SO2 and liquid 1,3-butadiene in a sealed bomb at 100 DEG C.ALSO:A nematocidal composition comprises a compound of the formula <FORM:0818709/VI/1> wherein X is halogen, Y is hydroxy, n is a number from 1 to 3 and m is a number from 0 to 4-n together with an inert solid carrier or dispersed in an inert liquid carrier or dissolved in an inert solvent. Fertilizers, insecticides, fungicides and herbicides may also be incorporated. Specified compounds are 3,4-dichloro - tetrahydrothiophene - 1, 1 - dioxide, 3 - chloro - tetrahydrothiophene - 1, 1 - dioxide, x,3,4 - trichloro - tetrahydrothiophene - 1, 1 - dioxide, 3,4 - dibromo - tetrahydrothiophene - 1, 1-dioxide and 3-chloro-4-hydroxy-tetrahydrothiophene-1, 1-dioxide.
