Compounds of the formulae I or II ##STR1## and processes for their preparation are described. In the above formulae, Z is a tetravalent aliphatic radical, which can be interrupted by hetero-atoms, or a substituted or unsubstituted tetravalent cycloaliphatic radical, which can contain hetero-atoms and/or can be fused to a benzene ring, A is --C(R.sup.4).dbd.C(R.sup.5)(R.sup.6) or --C.tbd.C--R.sup.5, especially --CH.dbd.CH.sub.2, R.sup.1 and R.sup.2 independently of one another are H, methyl, phenyl, --CN or Cl, or together are trimethylene, tetramethylene, ##STR2## R.sup.3 is a direct bond, C.sub.1-8 alkylene, cyclohexylene, phenylene or --CH.sub.2 -phenylene with the --CH.sub.2 group bonded to the N atom, R.sup.4 and R.sup.6 independently of one another are H, methyl or ethyl and R.sup.5 is H or C.sub.1-9 alkyl. The compounds of the formula I and II are valuable intermediates for the preparation of silicon-modified adhesion promoters.
本文描述了公式I或II的化合物及其制备过程。在上述公式中,Z是四价脂肪基,可以被杂原子中断,或者是取代或未取代的四价环脂基,可以含有杂原子和/或融合到苯环中,A是--C(R.sup.4)=C(R.sup.5)(R.sup.6)或--C.tbd.C--R.sup.5,特别是--CH.dbd.CH.sub.2,R.sup.1和R.sup.2彼此独立地是H,甲基,苯基,--CN或Cl,或者一起是三亚甲基,四亚甲基,##STR2## R.sup.3是直接键,C.sub.1-8烷基,环己基,苯基或--CH.sub.2-苯基,其中--CH.sub.2基与N原子相连,R.sup.4和R.sup.6彼此独立地是H,甲基或乙基,而R.sup.5是H或C.sub.1-9烷基。公式I和II的化合物是制备硅改性粘接剂的有价值的中间体。
