Abstract

Abstract Translated from German Silane mit SiC-gebundener Bernsteinsäureanhydridgruppe werden durch Umsetzung eines Bernsteinsäureanhydrid-Derivats der allgemeinen Formel <IMAGE> wobei m 2 oder 3 ist, mit einem Silan der allgemeinen Formel HSiRnX3-n, wobei R gleiche oder verschiedene, einwertige, SiC-gebundene organische Reste, X gleiche oder verschiedene Alkoxy- oder Alkoxyalkylenoxyreste bedeutet und n 0,1 oder 2 ist, in Gegenwart von die Anlagerung von Si-gebundenem Wasserstoff an aliphatische Mehrfachbindung förderndem Katalysator hergestellt. Silane der allgemeinen Formel <IMAGE> worin R, X und n die oben dafür angegebene Bedeutung haben, sind neu. Silanes with a SiC-bonded succinic anhydride group are reacted by reacting a succinic anhydride derivative of the general formula <IMAGE> where m is 2 or 3 with a silane of the general formula HSiRnX3-n, where R is the same or different monovalent SiC-bonded organic radicals, X denotes identical or different alkoxy or alkoxyalkyleneoxy radicals and n is 0.1 or 2, prepared in the presence of a catalyst which promotes the addition of Si-bonded hydrogen onto an aliphatic multiple bond. Silanes of the general formula <IMAGE> in which R, X and n have the meaning given above are new.
