    Abstract: There are disclosed two hydroquinone diethers having at least one acetylenic and halogen-substituted chain and exhibiting juvenile hormone and acaricide activity and which show unexpected activity on Tenebrio molitor and Tribolium confusum.The two hydroquinone ethers are obtained by:(a) reacting one mole of hydroquinone alkali metal salt with two moles of 1,5-dichloropent-4-yne, or equimolar quantities of an alkali metal salt of 4-phenoxy-phenol with 1,5-dichlorpent-4-yne; or(b) by reacting the hydroquinone alkali metal salt or the 4-phenoxy-phenol alkali metal salt with the indicated quantities of 1,1,1,5-tetrachloropentane and then dehydrohalogenating the condensation product with alkali metal carbonates or hydroxides in dimethylsulphoxide.

    Abstract: A process for preparing 1,1-dihalo-1,2,2,2-tetrafluoroethanes by isomerization of 1,2-dihalotetrafluoroethanes at their reflux temperature, by using, as a catalyst, the reaction product prepared "in situ" from an anhydrous aluminum halide with at least equimolecular amounts of the isomer, 1,1-dihalo-1,2,2,2-tetrafluoroethane in a medium consisting of 1,2-dihalotetrafluoroethane. The products find application as intermediates for pyrethroid insecticides.
