Application

1,3-Divinyl-1,1,3,3-Tetramethyldisiloxane Platinum(0) Karstedt's Catalyst, also known simply as Karstedt's catalyst, is a vital organometallic compound used in various scientific applications. This pale yellow liquid features a chemical formula of O[Si(CH3)2CH=CH2]2Pt and boasts a molecular weight of 381.48. As a platinum complex, it serves as an essential catalyst in hydrosilylation reactions, facilitating the addition of silicon-hydrogen bonds to unsaturated substrates. Beyond its application in synthesizing organometallic compounds like gold(I)-DVTMDS and palladium(II)-DVTMDS, Karstedt's catalyst plays a crucial role in the catalytic hydrogenation of aldehydes and ketones, as well as the oxidation of organic compounds. It is also employed in the preparation of phenol-functional silanes, which act as adhesion promoters, and as a precursor in developing highly active electrochemical systems, such as the Pt/SnO2 catalyst with a low metal load.
