ISOPROPENYLOXYTRIMETHYLSILANE Usage And Synthesis

Chemical Properties	clear colorless liquid
General Description	(Isopropenyloxy)trimethylsilane is an enol silyl ether. It participates as nucleophile in Lewis acid-promoted C3-nucleophile substitution of tetracyclic bromide. It is reported to participate in the total synthesis of (±)-powelline. It is reported to participate in dityltin bis(triflate) catalyzed Michael addition reaction of enol silyl ethers.
Purification Methods	Purify it by fractional distillation using a very efficient column at atmospheric pressure. It usually contains 5% of hexamethyldisiloxalane which boils at 99-101o, but is generally non-reactive and need not be removed. [Hauser & Hance J Am Chem Soc 71 5091 1952.] It has been distilled under N2 through a 15cm column packed with glass helices. Fraction b 99-104o is further purified by gas chromatography through a Carbowax column (Autoprep A 700) at a column temperature of 87o, and has a retention time of 9.5minutes. [Krüger & Rochow J Organomet Chem 1 476 1963-4.]
