Abstract
A process for the preparation of organosilanes functionalized in the 3-position, by the reaction of suitable allyl compounds with hydrogen silanes, using platinum catalysts having one or more sulfur-containing ligands.
Claims9
A process for the preparation of propyl silanes having a functional group in the 3-position, comprising:
- adding allyl compounds corresponding to formula (I)
- H2C═CH—CH2X (I)
- wherein X can be Cl, Br, I, F, CN, SCN, SH, SR, OH, NRR1 or OR, wherein R and R1, each independently of one another, denote (C1-C6)alkyl or (C3-C7)aryl,
- to silanes corresponding to formula (II)
- R2R3R4SiH (II)
- wherein R2, R3, R4, each independently of one another, denote hydrogen, halogen, (C1-C6)alkyl, (C1-C6)haloalkyl, (C3-C6)allyl, (C1-C4)alkoxy, phenyl, aryl or aralkyl, at reaction temperatures of between 0° C. and 200° C. and at pressures of between 800 mbar and 6 bar and in the presence of a platinum catalyst which has a platinum atom nucleus and one or more sulfur-containing ligands, wherein the one or more ligands are selected from the group consisting of sulfoxides, thiophenes and thiazoles.
