Abstract:
A method can selectively prepare a compound of formula (IV):, where each R 1  and each R 2  are independently selected from an alkyl group, an aryl group, a halogenated alkyl group, or a halogenated aryl group of 6 to 10 carbon atoms each R 3  is an alkane-diyl group, and each R 4  is hydrogen or an alkyl group. The method involves hydrosilylation of an organohydrogensiloxane oligomer with a carboxylic acid alkenyl ester using an iridium complex catalyst.

Claim (Index 4):
A method for preparing a product comprising:\n 1) combining ingredients comprising\n (A) an organohydrogensiloxane oligomer of unit formula (VI) (HR 1 2 SiO 1/2 ) 2 (R 2 2 SiO 2/2 ) e (R 2 HSiO 2/2 ) f , where subscript e is 0 to 20, subscript f is 0 to 20, each R 1  is independently an alkyl group of 1 to 6 carbon atoms, an aryl group of 6 to 10 carbon atoms, a halogenated alkyl group of 1 to 6 carbon atoms, or a halogenated aryl group of 6 to 10 carbon atoms; each R 2  is independently an alkyl group of 1 to 6 carbon atoms, an aryl group of 6 to 10 carbon atoms, a halogenated alkyl group of 1 to 6 carbon atoms, or a halogenated aryl group of 6 to 10 carbon atoms; \n (B) a carboxylic acid alkenyl ester of formula (II) \n \u2003where R 3  is an alkane-diyl group of 1 to 10 carbon atoms, and R 4  is hydrogen or an alkyl group of 1 to 6 carbon atoms; and (C) an iridium complex of formula (III)\n [Ir(R 5 ) b (R 6 ) c ] d , where subscript b is 1 or 2, R 5  is a 1,5-cyclooctadiene ligand or a 2,5-norbornadiene ligand, subscript c is 1 or 2, R 6  is a ligand that can be activated off the complex at a temperature less than the boiling point of the organohydrogensiloxane oligomer, and subscript d is 1 or 2; \n where the product comprises a compound of unit formula (VII) with at least 80 mole % selectivity based on all compounds formed by hydrosilylation of ingredients (A) and (B).
