Silicone, polyorganosiloxane, serves as an organosiliconreagent for palladium-catalyzed cross-coupling reactions. Treatment of polymethylphenylsiloxane, poly(alkenyl)methylsiloxane, or cyclic oligosiloxanes with various aryl iodides in the presence of silver(I) oxide or tetrabutylammonium fluoride and a catalytic amount of Pd(0) affords the corresponding coupling product in a good to excellent yield

The present invention relates to a method for preparing functionalized cyclosiloxanes of Formula (I), wherein R, R1, R2, m, n1 and n2 are as defined herein, comprising reacting (i) a cyclosiloxane of Formula (II) with (ii) a substituted acetylene of Formula (III) in the presence of a hydrosilylation catalyst. The invention further relates to methods for preparing biscyclosiloxanes by reacting the vinyl cyclosiloxanes obtained according to the described methods and the (bis)cyclosiloxanes obtainable according to the described methods.
