摘要
The invention relates to novel 2,2-dialkylpentane 1,5-diisocyanates, 2,2-dialkylpentane-1,5-diurethanes and 2,2-dialkylpentane-1,5-dicarbamoyl chlorides of the formula IMAGE in which R1, R2 denote identical or different linear C1- to C12-alkyl radicals, branched C3- to C12-alkyl radicals, branched C2- to C12-alkenyl radicals, branched C4- to C12-alkenyl radicals or the radicals R1 and R2 together denote an alkylene group having 4 to 7 C atoms which is unsubstituted or substituted by one to 5 C1- to C4-alkyl groups and X denotes an NCO-, NH-CO2R3-, NHCO2R4- or NHCOCl- group, in which R3 and R4 are identical or different and denote a linear C1- to C20-alkyl radical, a branched C3- to C20-alkyl radical or a C5- to C12-cycloalkyl radical. The 2,2-dialkylpentane-1,5-diurethanes are, for example, pest control agents and are suitable, as are the 2,2-dialkylpentane-1,5-dicarbamoyl chlorides, for example, for the preparation of 2,2-dialkylpentane 1,5-diisocyanates, which in turn are used for the preparation of compact or cellular plastics by the polyisocyanate polyaddition process.
