1-TRIMETHYLSILOXY-1,3-BUTADIENE Usage And Synthesis

Chemical Properties

clear light yellow liquid

Physical properties

bp 131 °C, bp 49.5 °C/25 mmHg; d 0.811 g cm?3.

Uses

1-Trimethylsilyloxy-1,3-butadiene is an easily prepared reactive diene for Diels–Alder reactions and other cycloadditions; reactive silyl enol ether for aldol and Michael reactions, and electrophilic additions.

Uses

1-(Trimethylsiloxy)-1,3-butadiene is commonly employed as diene in the Diels-Alder reaction.

Uses

1-Trimethylsiloxy-1,3-butadiene is a diene used in the Diels-Alder reaction.

General Description

Mechanism of Diels-Alder reaction between 1-(trimethylsiloxy)-1,3-butadiene and 4,6-dinitrobenzofuroxan has been studied using state-of-the-art computational methods.

Purification Methods

Purify it by fractional distillation and collect the fractions with the required 1H NMR. Store it under N2 — it is a flammable and moisture-sensitive liquid. [Caseau et al. Bull Soc Chim Fr 16658 1972, Belge Patent 670,769, Chem Abstr 65 5487d 1966.]
