Abstract: Novel compounds of the general formula ##STR1## wherein Z represents a substituted lower alkyl radical; each of R.sub.1 and R.sub.2 is hydrogen atom, a lower alkyl or a substituted lower alkyl identical with or different from Z and the functional groups NO.sub.2 and NR.sub.1 R.sub.2 can occupy all ring positions in relation to OZ, with the exception that if Z is .beta.-hydroxyethyl, --NO.sub.2 is in the 4 position and --N(R.sub.1)(R.sub.2) is in the 2 position then either R.sub.1 or R.sub.2 is other than hydrogen.The novel compounds are for dyeing human hair in a variety of yellow shades. The compounds of formula (I) may be used as aqueous or water-alcohol solutions to form dye compositions for dyeing human hair.

Abstract: Novel oxime ethers and oxime esters of the formula I given herein have various advantageous effects with regard to stimulation of plant growth, particularly in the early stage of development of the plant. Furthermore, such compounds have the property of rendering, in the sense of an antidote action, agricultural chemicals which would otherwise damage the plants (phytotoxic chemicals) more compatible with the cultivated plants. Herbicides that are insufficiently selective can be used for example in the presence of such oxime derivatives in specific cultivated crops for combating weeds, without disadvantageous consequences for the cultivated plants.

Abstract: Esters and thiolesters of amino acids, intermediates therefor, synthesis thereof, and the use of said esters and thiolesters and compositions for the control of pests.
