    摘要: There are described new pyrimidine derivatives of the general formula I ##STR1## in which n is 0, 1 or 2;R.sub.1 is(a) the group --CXR.sub.5, where X is oxygen or sulphur and R.sub.5 is hydrogen, a nitrogen or sulphur containing heterocyclic group, which can contain other hetero atoms, optionally substituted alkenyl, acyl, alkoxycarbonyl, alkyl substituted by aryloxy, or optionally substituted mono- or dialkylamino; or R.sub.5 is the group --NHR.sub.6, where R.sub.6 is substituted amino, substituted carbamoyl, optionally substituted alkylsulphonyl, acyl or arylsulphonyl, and when n is 0 or when X is sulphur, R.sub.5 can also be alkyl, haloalkyl, aryl, aralkyl, alkoxycarbonylalkyl or arylamino;(b) cyano or the group --CXYR.sub.7, where X and Y are the same or different and are oxygen, sulphur or optionally substituted imino and R.sub.7 is optionally substituted alkyl, aryl, acyl or a nitrogen or sulphur containing heterocyclic group, which can contain other hetero atoms; or(c) when n is 1 or 2 and at least one R.sub.4 group is haloalkoxy, R.sub.1 can be hydrogen;R.sub.2 and R.sub.3 are the same or different and are alkyl, andR.sub.4 is alkyl, alkoxy, halogen, haloalkyl, haloalkoxy, nitro or cyano. The compounds have fungicidal activity.

    摘要: This invention describes a new methylation or ethylation agent containing trimethyl aluminum or dimethyl zinc or triethyl aluminum as methyl or ethyl source, which additionally contains catalytic amounts of one or more copper(I) and/or copper(II) compounds as well as a process for the 1,4-addition of a methyl or ethyl group to an .alpha.,.beta.-unsaturated or an .alpha.,.beta.-double unsaturated ketone or an .alpha.,.beta.-unsaturated aldehyde using the agent according to the invention.By using only catalytic amounts of copper and a CKW (chlorinatedhydrocarbon)-free reaction medium, the new methylation/ethylation agent/process is distinguished by its environmental compatibility and it is, for example, suitable for the production of initial products for the synthesis of biologically effective compounds.
