    摘要： A process for preparing .alpha.,.beta.-unsaturated aldehydes of the general formula (I) ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 are independently a hydrogen atom, or an alkyl or alkenyl group with or without being substituted with a lower acyloxy group. The aldehyde of the general formula (I) is prepared by reaction between an allylic chloride of the following general formula (IIa) ##STR2## in which R.sup.1, R.sup.2 and R.sup.3 have, respectively, the same meanings as defined above, and an amine oxide selected from the group consisting of tri(lower alkyl)amine N-oxides of the formula,R.sub.3.sup.4 N.sup.+ O.sup.-,in which R.sup.4 represents a lower alkyl group having from 2 to 4 carbon atoms, and N-lower alkylmorpholine N-oxides of the following formula ##STR3## in which R.sup.5 represents a lower alkyl group having from 1 to 4 carbon atoms. Alternatively, the aldehyde of the formula (I) is obtained by reaction between an allylic chloride of the following general formula (IIb) ##STR4## in which R.sup.1, R.sup.2 and R.sup.3 have, respectively, the same meanings as defined above, and an amine oxide selected from the group consisting of tri(lower alkyl)amine N-oxides of the formula,R.sub.3.sup.4 N.sup.+ O.sup.-,in which R.sup.4 has the same meaning as defined above, and N-lower alkylmorpholine N-oxides of the following formula ##STR5## in which R.sup.5 has the same meaning as defined above, in the presence of an alkali metal iodide or a copper halide.

    摘要： Novel pesticidal compositions are comprised of a 2,2-dimethyl-3-(substituted ethyl)cyclopropanecarboxylic acid ester as the active ingredient, said cyclopropanecarboxylate having the structural formula: ##STR1## wherein X, Y and Z are the same or different and at least two of same are chlorine or bromine, with the remaining one being hydrogen, methyl, chlorine or bromine; R is an alcohol residue represented by one of the following structural formulae (II), (III), (IV) and (V): ##STR2## where A represents hydrogen, cyano, ethynyl or thiocarbamoyl; Q is hydrogen, chlorine, bromine, fluorine, methyl or trifluoromethyl; R.sup.1 is propargyl or benzyl; R.sup.2 represents 2-halogeno-3-phenyl-1-propen-1-yl, (dihalogenovinyloxy)phenyl, benzylphenyl, phthalimido, thiophthalimido, di- or tetrahydrophthalimido or dialkylmaleimido; R.sup.3 represents allyl, 2,4-pentadienyl, propargyl or benzyl.
