Abstract:
A process for the production of a 3-functionalized propyl silane comprising:adding an allyl compound of formula I H2C&boxH;CHâ€”CH2Xâ€ƒâ€ƒ(I), wherein X is Cl, Br, I, F, CN, SCN, SH, SR, OH, NRR1 or OR and R and R1, both independently of each other, mean (C1-C6)alkyl or (C3-C7)alkyl, to a silanes of formula II R2R3R4SiHâ€ƒâ€ƒ(II) wherein R2, R3, R4, all independently of each other, are hydrogen, halogen, (C1-C6)alkyl, (C1-C6)haloalkyl, (C3-C6)allyl, (C1-C4)alkoxy, phenyl, aryl or aralkyl, at a reaction temperature of 0Â° C. to 200Â° C. and a pressure of 800 mbar to 25 bar and in the presence of a platinum catalyst, wherein the silane (II) is brought into contact with the catalyst in a 3- to 100-fold molar excess in relation to the compound (I) to form an addition reaction.
