SYNTHESIS OF FLUOROCARBOFUNCTIONAL ALKOXYSILANES AND CHLOROSILANES
The subject of invention is the method of synthesis of fluorocarbofunctional alkoxysilanes and chlorosilanes of the general formula HCF2(CF2)n(CH2)mOC3H7SiR1R2R3 in which -n takes values from 1 to 12, m takes values from 1 to 4,-R1 stands for an alkoxy group or halogen, if R1 stands for an alkoxy gr...

Summary: | The subject of invention is the method of synthesis of fluorocarbofunctional alkoxysilanes and chlorosilanes of the general formula HCF2(CF2)n(CH2)mOC3H7SiR1R2R3 in which -n takes values from 1 to 12, m takes values from 1 to 4,-R1 stands for an alkoxy group or halogen, if R1 stands for an alkoxy group, then R2 and R3 can be the same or different and stand for an alkoxy group containing C=1-4, alkyl group containing C=1-12 or an aryl group, if R1 stands for a halogen, then R2 and R3 can be the same or different and stand for based on hydrosilylation of an appropriate fluoroalkyl-allyl ether with an appropriate trisubstituted silane of the general formula HSiR1R2R3 in the presence of siloxide rhodium complex [{Rh(OSiMe3)(cod)}2] as a catalyst. |
