<p>Preparation of organosilane compounds (I) comprises reacting silane compound (II) with alkene and/or alkyne (III) in the presence of iridium compound as catalyst and cocatalyst (inorganic-; metalorganic-; or organic oxidation agents), where the cocatalyst used in 0.5-5 wt.%, related to the total weight of (II) and (III). Preparation of organosilane compounds (I) of formula R 6>R 5>CH-R 4>CH-SiR 1>R 2>R 3>comprises reacting silane compound (II) of formula HSiR 1>R 2>R 3>with alkene and/or alkyne (III) of formula R 6>R 5>CH=CHR 4>in the presence of iridium compound as catalyst and cocatalyst (inorganic oxidation agent of oxygen, chlorine, bromine, iodine, peracid, peroxide, bromate, chlorate, iodate, perchlorate, potassium chromate, potassium dichromate, potassium permanganate, sodium peroxodisulfate, potassium perrhenate or potassium hexacyanoferrate(III); metalorganic oxidation agent of: ferricinium, ruthenium complex of formula [Ru(bipyridine) 3] 3 +>or iron complex of formula [Fe(phenanthroline) 3] 3+>; or organic oxidation agent of: aldehyde, acetone, methyl isobutyl ketone, acetylacetone, 1,4-cyclohexane dione, 1,3-cyclohexane dione, 1,2-cyclohexane dione, 1,9-cyclohexadecane dione, benzil, triketone, naphthoquinone, organic peroxide and peracid, crown ether, phosphane oxide, sulfone, tritylium salt or tropylium salt), where the cocatalyst used in 0.5-5 wt.%, related to the total weight of (II) and (III). R 1>-R 3>univalent Si-C bound, optionally halo substituted 1-18C hydrocarbon, Cl or 1-18C alkoxy; either R 4>-R 6>H, univalent 1-18C hydrocarbon (optionally substituted with F, Cl, OR, N(R) 2, CN or NCO), Cl, F or 1-18C alkoxy (where two of R 4>-R 6>residue together with the hydrocarbon forms a cyclic residue); or R 4>+R 5>bond between the C to which they are bound; and R : H or univalent 1-18C hydrocarbon.</p> |
