| titleOfInvention | Production of organosilicon compounds having azido groups |
| abstract | There are prepared azido groups containing organosilicon compounds of the formula ##EQU1## where R is a divalent hydrocarbon group having 1 to 8 carbon atoms which is free from ethylenically unsaturated bonds and whose carbon chain in a given case, is interrupted once by --O--, --S--, or --NR 3 where R 3 is hydrogen, methyl, ethyl, or phenyl, n R 1 is a univalent alkyl group having 1 to 3 carbon atoms, phenyl, benzyl, or tolyl, n R 2 is an alkyl group having 1 to 4 carbon atoms, phenyl, benzyl, or an alkoxyalkyl group having a total of up to four carbon atoms, n m is zero, 1, 2, or 3, and n n is zero, 1 or 2 whereby m<3-n, by reacting a halosilane of the formula n n X--R--SiR.sub.n.sup.1 (OR.sup.2).sub.3-n, II n n in which X is chlorine or bromine and the other symbols are as defined above with an azide of the formula n n MN.sub.3 III n n in which M is lithium, sodium, potassium, or ammonium, whereby in a give case, there is used a phase transfer catalyst whereupon there is carried out a hydrolysis or partial hydrolysis. Alternatively the hydrolysis or partial hydrolysis can take place first wherein there is first carried out the hydrolysis of one or more alkoxysilyl groups --OR 2 and subsequently there is carried out the reaction with the azide. The organosilicon compounds are valuable intermediates and also can be used as coupling agents for preparing silica reinforced rubber. |
