Abstract

The invention comprises dimethyl ether derivatives of the formula <FORM:1031532/C2/1> where R is a phenyl group, R1 is a phenyl group or an aromatic type helerocyclic radical in which the hetero atom is S, R11 is hydrogen or a phenyl group, R1 is an alkenyl radical, an O-or S- containing heterocyclic radical, a cycloaliphatic radical or a C1- 7 alkyl radical optionally substituted by halogen or an alkoxy group, R2 is hydrogen or a phenyl group, or R1 and R2 may be linked to form a saturated or unsaturated cycloaliphatic ring and R3 is hydrogen, provided that when R, R1 and R11 are all phenyl, and R2 and R3 are both hydrogen, R1 is not an alkoxymethylene group. The compounds are made by reacting in the presence of a tertiary nitrogenous base, a halide of the formula <FORM:1031532/C2/2> with a hydroxy compound of the formula <FORM:1031532/C2/3> or a hydroxy compound of the formula <FORM:1031532/C2/4> with a halide of the formula <FORM:1031532/C2/5> wherein Hal represents Cl, Br or I. The symmetrical ethers may also be made by catalytic dehydration of the corresponding carbinol. Specified compounds include those in which R1 is a thienyl group, R1 is a furfuryl, tetrahydrofurfuryl, tetrahydropyran or a thienyl group and R1 and R2 together are a cyclopentyl radical. The compounds are used as molluscicides and piscicides (see Division A5).ALSO:Molluscicidal compositions contain, as active ingredient, a dimethyl ether derivative of the formula <FORM:1031532/A5-A6/1> wherein R is a phenyl group, R1 is a phenyl group or an aromatic-type heterocyclic radical in which the hetero atom is S, R11 is hydrogen or a phenyl group, R1 is an alkenyl group, a o- or S- containing heterocyclic radical, a cyclo-aliphatic group or a C1-7 alkyl group optionally substituted by halogen or alkoxy groups, R2 is hydrogen or a phenyl group or R1 and R2 together form a saturated or unsaturated cycloaliphatic ring and R3 is hydrogen provided that when R, R1 and R11 are all phenyl, the group <FORM:1031532/A5-A6/2> is not an alkyl radical. The compounds 2-tetrahydropyran-2-yl-methyl trityl ether and cyclopentyl trityl ether are also used as piscidides. The ethers are used together with a solid or liquid carrier and/or a surface active agent. A stabilizing agent may be incorporated in the composition. The compositions may be used in conjunction with an attractant or bait.
