1,1,3,3-Tetramethyl-1,3-divinyldisiloxane (also referred to as tetramethyldivinyldisiloxane) is the organosilicon compound with the formula O(SiMe2CH=CH2)2.
Tetramethyldivinyldisiloxane is a colorless liquid that is employed as a ligand in organometallic chemistry and homogeneous catalysis.[1] The ligand is a component of Karstedt's catalyst. It was first prepared by hydrolysis of vinyldimethylmethoxysilane, (CH2=CH)Me2SiOMe.[2]
