Trimethylsilylacetylene Chemical Properties,Uses,Production

Chemical Properties

CLEAR COLORLESS LIQUID

Physical properties

bp 53 °C; d 0.695 g cm?3.

Uses

Trimethylsilylacetylene is a valuable reagent used in ethynylation by palladium(0)-catalyzed coupling/condensation with aryl and vinyl halides and triflates, or by nucleophilic attack of the corresponding acetylide on electrophilic centers; reacts with alkyl iodides, tin hydrides,6 and dichloroketene in a regioselective and stereoselective manner, participating in the following synthesis reactions: Ethynylations, Palladium(0)-Catalyzed Coupling Reactions,Reaction of Trimethylsilylacetylides with Electrophiles, Radical-Initiated and Transition Metal-Catalyzed Additions, Cycloaddition Reactions, Ethynylations, Cycloaddition Reactions, Further Transformations etc.

General Description

Laser-induced polymerization of gaseous ethynyltrimethylsilane was used for efficient chemical vapour deposition of polycarbosilane films. Ethynyltrimethylsilane acts as substrate for nickel-catalyzed cross-coupling with benzonitriles.

Purification Methods

Distil it through an efficient column. The IR has bands at max 2041 (CC) and 3289 (C-H) cm-1. [Kr.hnke & Goss Chem Ber 92 30 1959, Beilstein 4 IV 3937.]
