Patent number: 4417057Abstract: 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 independenty 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 compunds of the formula I and II are valuable intermediates for the preparation of silicon-modified adhesion promoters.Type: GrantFiled: June 26, 1981Date of Patent: November 22, 1983Assignee: Ciba-Geigy CorporationInventors: Dieter Lohmann, Martin Roth, Marcus Baumann
