Alkynyl, benzyl or phenyl, ethers and esters which are ring substituted with an oxy or a thio aliphatic chain. These ethers and esters are usful in killing and preventing the proliferation of insects by upsetting their hormonal balance.

Alkynyloxy-phenyl derivatives

Ethers, esters and amides of dodeca-2,4-dien 1-ols or 1-oic acids which have a methyl or ethyl side chain at the 11-position which are useful in killing and preventing proliferation of insects, by upsetting their hormone balance and a process for preparing these ethers, esters and amides including intermediates in this process.

Epoxy dodecadienamides

Alkynyl, benzyl or phenyl, ethers and esters which are ring substituted with an oxy or a thio aliphatic chain. These ethers and esters are useful in killing and preventing the proliferation of insects by upsetting their hormonal balance.

9-[2-(1-alkoxy-ethyl)-5,5-dimethyl-cyclopent-1-en-1-yl]-3,7-dimethyl-nona-2 ,4,6,8-tetraen acid compounds are disclosed which are useful for the topical or systemic treatment of dermatological disorders.

9[2-(1-Al

Phenyloxy, phenylsulfinyl, phenylthio, phenylsulfonyl, benzyloxy, benzylthio, benzylsulfinyl, or benzylsulfonyl, alkyl or alkenyl derivatives wherein the alkyl or alkenyl group contains at least 7 carbon atoms which are useful in killing and preventing proliferation of insects by upsetting their hormone balance.

Phenyl derivatives

Propynyl benzyl ethers having juvenile hormone-like activity which are 4-halogen, lower alkyl, lower alkoxy or propynyloxy substituted or 3,4-lower alkylenedioxy substituted and which can also be 3,5- and/or .alpha.-substituted, and insecticide compositions that include at least one propynyl benzyl ether and that can also include a conventional insect-poison.
