Abstract: Preparation of 3-functionalized propylsilanes (I) comprises addition of allyl compounds (II) to silanes (III) at 0-200 degrees C and 800 mbar to 6 bar in the presence of a platinum catalyst that has ligand(s) containing sulfur. Preparation of 3-functionalized propylsilanes (I) comprises addition of allyl compounds of formula (II) to silanes of formula (III) at 0-200 degrees C and 800 mbar to 6 bar in the presence of a platinum (Pt) catalyst (IV) that has ligand(s) containing sulfur: X = chlorine (Cl), bromine (Br), iodine (I), fluorine (F), cyano (CN), thiocyanato (SCN), mercapto (SH), organylthio (SR), hydroxyl (OH), amino (NRR ) or organyloxy (OR); R, R = 1-6 carbon (C) alkyl or 3-7 C aryl; R , R , R = hydrogen (H), halogen, 1- C (halo)alkyl, 3-6 C allyl, 1-4 C alkoxy, phenyl, aryl or aralkyl. An Independent claim is also included for the use of (IV) in this addition reaction.
