Abstract: Benzyl esters of the formula ##STR1## in which n is 1,2,3,4, or 5,R.sup.2 is hydrogen, C.sub.1-4 -alkyl, cyano or ethynyl,R.sup.3 is radical of a carboxylic acid customary in pyrethroids or pyrethroid-like compounds, andat least one R.sup.1 is fluoroalkoxy or fluoroalkylmercapto, or two together are fluoromethylene- or fluoroethylene-dioxy, and the others, if present, are hydrogen or various radicals,which possess arthropodicidal properties. Various alcohols, amines, aldehydes, halides, and the like, corresponding to the alcohol moieties of the esters are also synthesized.

Abstract: There is disclosed a novel process for preparing a number of cinnamaldehyde derivatives. These cinnamaldehyde derivatives can be reduced to dihydrocinnamaldehyde derivatives, a number of which are commercially important in the preparation of fragrances. The invention is also directed to a number of novel intermediates and their preparation.

Abstract: Novel .alpha.-ethynyl- and .alpha.-vinyl 3,4-disubstituted phenylalanines are disclosed. The compounds have pharmaceutical activity.

Abstract: The present invention relates to 2-arylpropyl ether or thioether derivatives represented by the following general formula [I]: ##STR1## wherein Ar stands for an aryl group, R stands for a methyl or ethyl group, Y stands for an oxygen or sulfur atom, and B stands for a group represented by the following formula [II]: ##STR2## or the following general formula [III]: ##STR3## wherein Z stands for an oxygen or sulfur atom or a carbonyl or methylene group, R.sup.1 stands for a hydrogen or halogen atom or a lower alkyl group or a lower alkoxy group, and n is an integer of from 1 to 5 with the proviso that when n is 2 or more, the groups R.sup.1 may be the same or different, and also to processes for the preparation or these ethers of thioethers and a use of these ethers or thioethers.These compounds of the present invention have excellent insecticidal and acaricidal activities while the toxicity of these compounds are very low.
